Code Creatures:::...

Alas Code Creatures is no longer officially supported as a benchmark, which in these days of unfair optimisations is all the more reason to use it. Of course we're not likely to find CPU's specifically optimised for benchmarks.........are we? Not yet at least.


Athlon64 X2 4800+

 


Athlon64 4000+

It's close, but for a CPU not sold on its gaming merits it's great to see that's not because it has none.

Overclocking:::...

I've already spoken about overclocking when I covered operating temperatures, and to remind you I was only able to run fully stable at 215MHz (12x215MHz = 2580MHz). 220MHz (12x220MHz = 2640MHz) was possible for all things 2D but gaming was a touch flaky at this point. I've heard of better results than this so you may have better luck.

I didn't move from default voltages during overclocking, partly because when I tried it didn't seem to help any, and partly because overclocking such early parts is rarely an accurate reflection of what's to come, certainly not when I'm running the top-end 2.4Hz part to begin with.

At 215MHz the performance improvement was predictably small. Having said that, we also need to remember that any speed increases are per core, therefor when it comes to multithreaded application a 15MHz overclock is effectively a 30MHz overclock.

First let's look at Far Cry:


Far Cry Overclocked Results

 

I was quite surprised by the increase from Far Cry. Doom3 however didn't fair quite so well.


Doom 3 Overclocked Results

 

TMPGEnc:::...

 


200MHz Base Frequency

 


220MHz Base Frequency

The increase of 20MHz rewards us with 20 seconds wiped off the encoding time. Remember though, that's an extra 240MHz per core, 480MHz effective in dual-threaded applications like this one.

CliBench SMP MK III:::...

Clibench meanwhile running 2 threads shows around 10% increase in performance in exchange for the 10% increase in base frequency, though again we should remember that that's 5% per core effectively.

 

The Hidden Facts:::...

One thing that no number of benchmarks can convey is the "feel" of a multi-processor system.

I've grown accustomed to sitting and waiting for resource-intensive apps to finish before opening anything else. Being able to fire up and play a game while I have a spyware scan going on or have a movie being encoded was quite a buzz. It's just a shame that so many processor cycles are spent defending our systems against idiots when they could be doing something productive.

Compatibility:::...

AMD now have their Athlon 64 X2 processor web page online. From here you can get details on all compatible motherboards as well as white papers, product briefs and much more. You can get there by going to:

Conclusion

The 3DVelocity 'Dual Conclusions Concept' Explained: After discussing this concept with users as well as companies and vendors we work with, 3DVelocity have decided that where necessary we shall aim to introduce our 'Dual Conclusions Concept' to sum up our thoughts and impressions on the hardware we review. As the needs of the more experienced users and enthusiasts have increased, it has become more difficult to factor in all the aspects that such a user would find important, while also being fair to products that may lack these high end "bonus" capabilities but which still represent a very good buy for the more traditional and more prevalent mainstream user. The two categories we've used are:

The Mainstream User ~ The mainstream user is likely to put price, stock performance, value for money, reliability and/or warranty terms ahead of the need for hardware that operates beyond its design specifications. The mainstream user may be a PC novice or may be an experienced user, however their needs are clearly very different to those of the enthusiast, in that they want to buy products that operate efficiently and reliably within their advertised parameters.

The Enthusiast ~ The enthusiast cares about all the things that the mainstream user cares about but is more likely to accept a weakness in one or more of these things in exchange for some measure of performance or functionality beyond its design brief. For example, a high priced motherboard may be tolerated in exchange for unusually high levels of overclocking ability or alternatively an unusually large heat sink with a very poor fixing mechanism may be considered acceptable if it offers significantly superior cooling in return.

 

The Mainstream User ~

Dual-core processors may be being positioned as a specialist part at the moment, but the frustrating reallity is they're needed right now by just about all of us. Why?, well if your PC is protected to anything like the level it needs to be in order to stay safe, there's probably already plenty of work to keep one of those two CPUs at least partially occupied. If you've ever had a scheduled anti-virus scan initialise in the middle of a demanding game you'll know exactly what I'm talking about.

Prices are high at the moment but if you can afford to go dual-core then that's precisely what I suggest you do.

The scores below don't necessarily represent this high-end model, but are more a reflection of the technology on offer throughout the X2 range. Mainstream users may find the cheaper, slower versions perfectly adequate.

NA

 

The Enthusiast ~

I think the numbers say it all. Until multithreaded gaming becomes mainstream there's not much point buying the X2 purely for that reason alone, but considering the general benefits from running a multitasking OS on dual-core CPUs it's hard to not want to eqip your system with one. Any game will benefit from dual cores when run alongside other CPU-intensive tasks, whether they're multithreaded or not.

The X2 adds both stamina and speed to the PC. The speed is mostly yet to come, the stamina is available right now, or more accurately, some time towards the end of June if AMD's schedules hold.

If you want raw power at your fingertips, were considering a dual CPU system, are on the verge of a system upgrade and have the cash to cover one or use prosumer level digital media manipulation software, then the X2 has your name on it.

We're always looking for ways to make our reviews fairer. A Right To Reply gives the manufacturer or supplier of the product being reviewed a chance to make public comments on what we've said. They can explain perhaps why they've done the things we were unhappy with or blow their own trumpet over the things we loved. It's easy for us to pick a product apart but sometimes things are done a certain way for very specific reasons.

Should AMD decide to exercise their "Right To Reply", we'll publish their comments below:
