AMD Phenom 9600 Black Edition Quad Core CPU Page: 1
Introduction
 
AMD have been playing catch-up with Intel ever since Intel's Core architecture reared it's not so ugly head. With the X2 range of processors lagging behind their Core2 counterparts and Intel releasing a Quad Core, AMD had to get a chip out and fast.
 
Unfortunately, they didn't manage fast, but they did manage to get one out. Phenom is a native Quad Core chip which is fantastic, but it's launch was marred by reactively low clock-speeds. The Phenom 9600 we have here today kicks us off at 2.3GHz and there is a 2.4GHz Phenom 9700, a 2.6GHz par - Phenom 9900 as well as a 2.22GHz Phenom 9300.
 
AMD quad core
 
 
What's new?
 
Well the thing is, not a whole lot is actually new with the new CPU. AMD "enthusiasts" will point out the fact that pipeline can cope with about 33% more traffic and that some of the SSE4 (AMD call it the SSE4a), instruction set is now able to be handled by Phenom.
 
AMD have gone with a three tiered cache level for their Phnom processors with the L3 being labelled "Smartcache", with 512K per core adding up to a total of 2MB L3 cache. This would be hunky-dory, except for the fact that (in very extreme circumstances), there is a bug called the L3 cache Translation Lookup Buffer (TLB) erratum which can cause a system crash. There's a BIOS fix for this, but this means a 10-15% performance drop. Seeing as we didn't use the BIOS fix in this review and during use of the CPU and never once experienced the error I think your fairly safe not worrying about it....unless you need 100% total stability all of the time.
 
AMD have also pumped up their HyperTransport bus to 2.0GHz from 1.0GHz seen in their previous CPU's.
 
Some pretty cool new virtualisation features have also been added, which we went through in our Barcelona Article.
 
 
Pretty in...Black...
 
The Phenom AMD supplied us with was the "Black Edition" 9600 with an unlocked multiplier. By all accounts it's a good thing too as rumours are circulating that Phenom's don't overclock too well.

Test Setup
 
We debated for quite some time as to how to test AMD's Phenom and in the end decided that we would compare it to Intel's Q6600 due to the comparative price of both the processors.
 
I also debated about whether I wanted to use the TLB BIOS fix in the review and after running through a whole set of benchmarks and 48 hours of stress testing without a crash and without the fix, I decided to feature this review without the fix. Some may agree with this decision, some may not, I hope either way you find the results interesting!

Overclocking
 
Overclocking was almost a totally non-familiar experience to begin with, until I remembered my socket 939 overclocking days! The BIOS of the Asus board we used was thorough and had a lot of options so I decided to get in there and see how this unlocked Black edition could do.
 
I haven't included a Max FSB graph here as they don't compare very well, but the Max FSB I could attain on the Phenom was 210MHz using the BIOS and 220MHz using AMD's overdrive tool, pretty disappointing considering I used to be able to get speeds in excess of 300FSB out of my old X2 and AMD 64 CPU's.
 
Max OC
 
Unfortunately I only managed a measly 200MHz from this B2 stepping Black Edition Phenom CPU. Anything else froze the system up. I did try using AMD's Overdrive Tool (which is a handy little gadget for information about the CPU), but this also topped out at 2500Mhz. Compare this to the Intel and, well, there's no comparison.

The results show that the Core 2 Quad CPU has the run of the benchmarks in pure power but, as usual, the AMD CPU has a whole shed-load of memory bandwidth.
 
 
everest
 
Everest is in many ways similar to Sisoft Sandra. Focusing mainly on Software and Hardware information reporting, Everest also comes with a benchmark utility suitable for testing the read, write and latency performance of the memory subsystem. Each of these benchmarks were performed a total of 5 times with the highest and lowest scores being discarded and an average calculated from the remaining 3.

ViMark
 
ViMark is the latest addition to the OC3D motherboard testing process and a relatively new benchmarking application in general. Designed to take the inaccuracies and guesswork out of measuring the time taken to encode video files, ViMark produces easily comparable and consistent results for encoding raw video into Windows Media, Quicktime, AVI and Gif formats. As always, a total of 5 benchmark runs were performed with the highest and lowest scores removed and an average calculated from the remaining 3 scores.
 
ViMark - wm
 
vimark - qt
 
vimark - avi
 
ViMark - GIF
 
ViMark shows us that the Core2Quad generally beats out the slower Phenom CPU and often by a margin.
 
 
7-Zip
 
7-Zip is an open source winzip-style file compression utility that has the ability to compress and decompress many file formats including it's own .7z compression scheme. 7-Zip also comes complete with its own benchmarking utility for gauging the compression and decompression speed of the system that it is installed on.

Cinebench
 
Cinebench 10 is a benchmarking tool based on the powerful 3D software Cinema 4D. The suite uses complex renders to guage the performance of the entire PC system in both single-core and multi-core modes. Testing was performed a total of 5 times with the highest and lowest results being omitted and an average created from the remaining 3 results.

cinebench multi cpu
 
cinebench opengl
 
Cinebench shows that whilst the Phenom does fairly well in multi-threaded applications, the pure speed of the Intel chip prevails.
 
 
3dm05  3dmark06
 
3DMark is a popular synthetic gaming benchmark used by many gamers and overclockers to gauge the performance of their PC's. All 3DMark runs were performed a total of 5 times with the highest and lowest results being removed and an average calculated from the remaining 3 results.
 
3dmark05
 
3dmark06
 
In a strangely reversed situation, the Core 2 Quad is beaten in the 3DMark tests by a few points. I'm not quite sure exactly why this is the case, although 3Dmark06 saw the CPU utilization up to 100% across all four cores

quake 4
 
Quake 4 is a game built on the Doom 3 engine. Benchmarking was performed using Quake4Bench and a custom timedemo recording along with 0xAA, 0xAF settings at a resolution of 1024x768. The benchmark was set to run a total of 5 times, with Quake4Bench automatically calculating an average result at the end of the run.
 
quakee 4 bench
 
Quake 4 benchmarking showed that during real life gaming situations, the Phenom is a little off the pace of the Intel Quad.
 
 
F.E.A.R.
 
F.E.A.R. is a game based on the Lithtech Jupiter EX engine. It has volumetric lighting, soft shadows, parallax mapping and particle effects. Included in the game is a benchmark facility that taxes the entire PC system. This benchmark was run a total of 5 times, with the highest and lowest results being excluded and an average being calculated on the remaining 3 results.
 
F.E.A.R.
 
F.E.A.R. ran a little slower again than the Q6600.
 
 
Bioshock
 
Bioshock is a recent FPS shooter by 2K games. Based on the UT3 engine it has a large amount of advanced DirectX techniques including excellent water rendering and superb lighting and smoke techniques. All results were recorded using F.R.A.P.S with a total of 5 identical runs through the same area of the game. The highest and lowest results were then removed, with an average being calculated from the remaining 3 results.
 
Bioshock
 
Bioshock showed the least difference between the games, with the Phenom 9600 keeping up pretty well with the Q6600.
 
For fairness I have to say that once the games are turned up to full, with all details enabled and the resolution at 1920 x 1200, there is a much less marked difference between the two Quad Core processors.

Conclusion
 
AMD Phenom is a good attempt at making a Quad Core CPU and had it been out before Intel brought out their Quads perhaps we would have seen a high takeup of those CPU's.
 
However, in the current climate, armed with Intel Core 2 Quads that compete in price as well as dominating in performance it's tough for AMD to make a mark. The Phenom Black Edition is a special edition unlocked multiplier CPU, but in all honesty this doesn't make the slightest bit of difference when overclocking so it's almost a moot point. Gone are the days when the FX series offered hardcore overclockers real unlocked overclocking potential.
 
Priced at around £150, the Phenom's are competing with the Q6600 in real monetary terms, not good for AMD.
 
I will say that those of you with AM2 boards need look no further, drop a Phenom into the system and you'll be smiling at the performance increase. However, for those building a new system we can't rightly say "go and buy it" - rather that you should probably look at a Q6600 which seem to do 3.6GHz all day long on low volts.
 
I hope AMD build on the Phenom and tweak and improve and release a non-bugged, improved B3 stepping Phenom that really gives us something to be hopeful about.
 
Of course, I haven't even mentioned Nehalem yet....
 
The Good
+ Excellent upgrade path for socket AM2 users
+ Fantastic bandwidth
 
The Mediocre
* Gaming performance not too bad
* Multi-tasking is responsive
 
The Bad
- Loses out badly to Intel on performance
- Awful overclocking potential
- Needs a price drop
 
 
Thanks to AMD for the review sample
