Cub's new PC buyers guide... Part 1: CPUs
Posted: June 30, 2005 • 7:01 am
Well, I am at work (the boring non fun one) and decided that with all this new whiz bang technology coming out I should share some valuable information with my friend here so that I can help people get the best out of what technology has to offer nowadays.
This guide is useful for hardcore gamers all the way through to TOGs, and if it is not in your best interest to buy a whiz bang machine in the future you may treat these guides as Modern PC 101.
Anyway, here goes:
Part 1: CPUs
_________________________
Of course, when looking for a new processor you cannot bypass the fact that you will be looking for one of two brands: Intel and AMD…
Intel Processors:
For Intel, processors these days range between the Celeron (low budget mainstream) all the way to the Pentium D (Intel’s latest dual core CPU offering). Intel processors have been praised for their stellar performance in workstation style applications, but you will rarely find hardcore gamers with Intel CPUs, purely due to the fact that AMD owns the gaming market in terms of gaming performance. Anyway, lets have a look at a quick rundown at all Intel has to offer and how each model benefits the user:
Intel Celeron:
This is Intel’s low-budget mainstream offering. This processor is catered to the home/office user who really only needs the PC for surfing the net, sending e-mail and listening to the odd Mp3… however, as a gaming CPU, this is probably the least favourable processor of the lot (Intel and AMD)… its lack on on-die cache and lack of features make it painfully slow for video, gaming and any other medium scale demands. Even with the most whiz-bang graphics accelerator around, your computer’s performance will be servery limited by this CPU.
The Celeron D is pretty much the same except for a faster Front Side Bus memory controller (FSB) @ 533 mhz, supporting PC4400 Ram arrays and a 90nm process technology… but the bottlenecks caused by all other aspects of this processor make the Celeron D a souped up Celeron with no real benefits, except for the ability to load e-mail quicker.
Pros: Really cheap
Cons: Gaming with even the best hardware is a painful experience. No multitasking. No 64-but support.
Speeds: Usually between 2.4 and 3.2Ghz
Price: Between $60-120
Intel Pentium 4 and Pentium 4 with Hyper Threading:
Well, considering that if you were going to buy a Pentium 4 you might as well get one with Hyper Threading, we will talk about that…
Hyper Threading is a great technology from Intel, which makes multi-tasking much less of a headache. Hyper threading basically works by filling the gaps created by the processing of one application with the execution of another in a parallel fashion, rather then a serial one. The idea is kind of like a zipper, where each process takes it turn in efficiently calculated intervals to pass through the CPU. The end result is a fully utilised CPU.
From my personal experiences with Hyper Threading, it is a great tool. Especially if you like to surf the net whilst you are rendering a video… or hosting a game server, and playing on it at the same time. However, HT does NOT double the speed of the processor. As said above, it merely fills in the gaps created by one process with the other. So don’t expect to be able to turn your 3.6ghz HT processor into a 7.2Ghz supercomputer.
Now, for gaming, the Pentium 4 with HT is a very respectable gaming processor. The P4 is also available in as high as 3.8Ghz… that means you should not have to worry too much about limiting you other whiz-bang hardware.
If you are fortunate enough to be able to afford a P4 Extreme Edition, which comes with a whopping 2mb Level 2 cache and a 90nm process technology, you will be pretty close to heaven. However, its lack of 64-bit computing allows AMD Athlon 64 equivalents to maintain the gaming performance crown.
Pros: Hyper Threading. Very Fast. Great for design applications, and games.
Cons: Can run very hot. More expensive than their AMD equivalents. No 64-bit support
Speeds: Usually Between 2.6 and 3.8Ghz
Prices: Between $120 (2.4Ghz) to a whopping $1,000 for the 3.4Ghz EE
Pentium D and PD EE:
Welcome to Intel’s flagship. The Pentium D in all its Dual Core 64-bit goodness! Intel, along with AMD have started a revolution with their new range of Dual Core CPUs.
Now I know that you are thinking, why dual core when we can just use HT. Well remember what I said above, HT uses a swap style execution process to run multiple threads through one processor. Imagine of you could have 2 cores, both running at 3.4Ghz, without the need to calculate parallel threading. Not only that; imagine two 64- bit cores each capable of HT! The opportunities are making you woozy aren’t they? Basically, the main benefits of a dual core processor are as follows:
For gaming: When game designers are able to implement dual processor support into their games, you could have one processor dedicated to AI and one dedicated to physics! With simple HT this was not possible because you cannot run two separate threads of information from the one application. With Dual cores you can!
For workstations: Aside from the fact that most workstation applications already support dual processors, with dual cores, you could hypothetically render a film whilst you are editing it. Or render an animation in 2X the speed! Which would not be done with HT because once again, HT only works when swapping to separate application threads.
The processor is not a 6.8Ghz processor per say, but you will be able to run two processes, this time within the same application at 3.6Ghz without compromise.
As for the Extreme Edition Pentium D… it’s like the PD (no, not Pandora Directive) with the sunroof option… it supports HT on each processor… the normal Pentium D does not. So technically, you could run 4 separate applications at once without compromise. However, this spears rather impossible considering that the computers memory is already handling 2 separate instructions. However it is a nice touch… in theory.
Get ready for a hefty price tag though, these babies are not cheap:
Pros: 64-bit support. Very fast. 2 cores… duh! HT X2 on the Extreme Edition.
Cons: Expensive… not to many current application support dual cores, especially not gaming.
Speeds: Between 2.8-3.2 Ghz X2
Prices: $260-$1050 (EE)
AMD Processors (Advanced Micro Devices):
AMD has been dubbed the undisputed leader of the gaming market… you would actually find it hard to spot a hardcore gamer not using and AMD. AMD processors range between the Sempron (mainstream) to the FX and the X2 (High end).
One word comes to any gamers mind when AMD is topic if processors… “Overclocking!â€
AMD are stellar overclockers, and with their latest flagship, the FX-57… they have proclaimed this processor a viable overclocker. For the first time in history a company has the confidence to encourage it’s users to overclock their processor, and because they run a lower clock speeds and lower temperatures, overclocking on stock components is as simple as raising the FSB or multiplier using the overclocking software that comes with your mainboard.
AMD processors don’t need to run at high clock speeds to be able to process efficiently. In fact, you rarely find and AMD processor above 2.4Ghz. So why are they called 3000+, 3800+ and 4000+ and so on…?
Well, AMD figured that if they marketed their processors based purely on clock speeds, to the average Joe they would appear inferior. And considering nowadays clock speeds only account for 50% or the processors key workload, they decided to base their numbers purely on performance…. mainly based on a kind of Intel equivalency index.
For example: an AMD Athlon 64 3200+, even though it runs at 2.2Ghz, is roughly the equivalent of an Intel 3.2Ghz. Or at least that was the case 2 years ago… now optimisations in the AMD processor range are so advanced that an Athlon 64 3200+ is more comparable to a P4 3.8, thanks to its 64-but technology and other enhancements.
Another great thing about AMD is the prices. AMDs are usually vastly cheaper then Intel CPUs, yet they don’t show any compromises on performance.
Anyway, lets take a look at some of the AMD models:
Sempron:
This is a fairly new model from AMD that was designed to replace the Athlon XP range. It uses a 32-bit technology, and has between 256k and 512k of on die cache. These processors are efficient, and run significantly cooler than their Intel equivalents. They overclock fairly well and are great for the mainstream/semi-pro gamer/user. An AMD Sempron can best be compared to an Intel Pentium 4. However, P4s tend to be better in design applications like Photoshop or Adobe Premiere purely dur to the fact that they support HT and design applications crave clock speed above efficiency. The Sempron is a great, cheap processor for the home user who wants to not only check e-mail, but also game at satisfactory speeds.
Pros: Runs cool and quiet. Can overclock well. Tends to perform better in games then it standard P4 equivalent. Very cheap… and leaves the Celeron behind in ruins!
Cons: No real multitasking support. Generally slower then a P4 in design applications. Can cause limitations upon other hardware such high end graphics accelerators. No 64-bit support.
Speeds: 2200+ to 3300+
Prices: $58-$130
Athlon 64:
AMD was the first to embrace 64-but computing on the PC. The AMD 64 have been known for their stellar gaming performance and overclocking abilities. They are also relatively cheap.
Whilst a lot of games don’t fully support 64-bit computing the AMD 64 is a solid performer. If you were looking for a relatively cheap processor with amazing gaming performance the A64 is a valuable asset. They are capable of both a Level1 cache of 128kb and a Level2 cache of 1mb for great efficiency, and you can overclock a 3200+ to as high as 3600+ speeds on standard air-cooling.
Even though the gaming performance of the A64 can almost always top its Pentium Equivilant (even without HT) it still lacks multitasking support. Also, you are sill better of with a high end P4 for design applications… however, AMD 64 processors provide several speed advantages in Windows XP compared to the Pentium 4 and are a more future proof option.
For the conscious pro gamer who wants excellent performance, without the hefty price tag, the AMD Athlon 64 is worth every penny.
Pros: Great for gaming. Great performance/price ratio. Overlock like blazes! 64-bit support. Performance enhancements available with Windows XP 64-bit edition.
Cons: No multitasking support. Often only marginally slower in design applications compared to Intel.
Speeds: Between 3000+ (2.1Ghz) and 4000+ (2.4Ghz)
Prices: $119-$450
Athlon 64 FX:
Proclaimed the “Gods of gaming†the FX series is just un-matched in gaming performance. In fact, there is not one single processor Pentium that can top an FX. The models come in 4 flavours, FX-51, 53, 55 & 57, ranging between 2.2Ghz and 2.8Ghz. What makes the FX so fast is not only its high performance on-dye Cache levels (similar to the Athlon 64) but its integrated DDR memory controller. Any gamer would tell you that the speed in which the processor can communicate with the Memory and other hardware such as the Video Accelerator is very important, and the FX range handles such demanding gaming requirements with ease, coupling the integrated memory controller with it’s Hyper Transport technology.
However, such performance comes at a price. The FX is basically AMD’s Extreme Edition, but with 64-bit support. However, if you ask any gamer what is the best processor man can buy for gaming, he would tell you without a doubt: “The FX-57â€.
Now all this talk of gaming, lets get to the home application user. The FX range is probably the first in the AMD range to provide viable competition to Intel in design applications. However, with every new FX processor, there is another Intel Extreme Edition around the corner. However, considering that the FX range can match the Intel equivalents with single threaded computing it stands to reason that a designer with a love of gaming could find the FX range a valuable consideration. Especially when if you are spending this kind of money on a CPU (Intel) you might as well spend the same kind of money and get stellar gaming performance on the side.
However, all things aside, the FX is not a multi-threaded processor, a hence will not multitask as well as it’s Intel equivalent. However, it becomes a decision of whether you value fast single threaded computing compared to multi-threaded computing. Of course, you decision may swing either way depending on your needs.
Pros: Unbeatable in gaming performance. Can match Intel for single threaded design applications. 64-bit capabilities. The FX-57 proclaimed the world’s best overclocker.
Cons: Expensive. No Multi-tasking.
Speeds: 51 (2.2Ghz) 53 (2.4Ghz) 55 (2.6Ghz) & 57 (2.8Ghz)
Prices: $500-$1,200
Athlon 64 X2
AMD not only was the first to implement 64-bit computing into PCs but also lead the dual core revolution with the Athlon 64 X2 range. Some would say finally AMD have a processor capable of processing multiple threads at once, and about time. It was always AMDs philosophy that multithreading should be done on multiple processors, hence their push for Dual Opteron workstation setups… but that’s another story.
Lets take a brief look at the X2 which ranges between 4200+ (2X 2.2Ghz w/512kb X2 on-dye cache) and 4800+ (2X 2.4Ghz w/1024kb X2 on dye-cache).
Now there is where things get interesting, AMD was always just behind Intel in workstation applications, mainly due to its lack of multi-threaded support. But now that both the X2 and the Pentium D are on par… how do they both fair? Funnily enough, both are fairly even. Each have 64-bit computing and 2 physical processors. The only difference is AMDs X2 runs a lot cooler and at lower clock speeds, and has the ability to overclock comfortably. The differences in performance between the Intel and the AMD dual core processors depends on what type of applications you use, you if you are in the market for a dual core, I suggest reading a few program specific reviews to muster up a discission as to which processor suits you and your needs.
However, gaming is a different story. AMD, as stated above, has always has stellar gaming performance with it’s single core 64 bit processors. The X2 is no exception. It’s performance & overclockability make it a great choice for future conscious gamers looking forward to dual-core gaming with engines capable of taking advantage of it such as the upcoming Unreal Engine 3. However, the X2 is still behind the FX range in gaming purely due to the fact that no games at this stage support multiple CPUs and so according to most games you are gaming with only 1X AMD Athlon 64 processor. However, the X2 is a valuable upgrade for a current Athlon 64 user wishing to prepare for the next generation of Dual Core compatible games.
Pros: 2X very fast cores. Finally, multi-threaded support! Great gaming performers for current and upcoming dual core compatible games. Runs at lower temperatures. Overclockability.
Cons: Not as fast as the FX-55 with gaming and single threaded computing. Pretty darn expensive.
Speeds: between 4200+ (2X 2.) and 4800+ (2X 2.4Ghz).
Prices: $585-$1065
In conclusion...
We’ve just about covered what both Intel and AMD have to offer in CPU land. There are of course other workstation processors out there, such as the Xeon and Itanium from Intel and the Opteron for AMD… but of course, these processors are workstation models and are impractical for anything except high-end CAD-CAM, design and server applications.
In the end, the best way to decide which processor best suits you is to follow this method.
1. Find your price range/limitation
2. Determine your needs
3. Assess your wants
4. Determine which processor best suits you
5. RESEARCH (reviews, benchmarks and forums)
6. Decide
IF you follow this guide, you should be pretty much safe when it comes to choosing the right CPU for your needs.
I hope this guide has proved beneficial for everyone and if there are any questions, just post them here!
