Test System And Benchmarks
We didn’t run our entire benchmark suite for this little project. After all, our main goal in running tests was to verify that what we were seeing in CPUz and Everest was correct.
|AMD Phenom II X4 810 (Deneb) 2.6 GHz, 4 MB L3 cache
|Row 1 - Cell 0
|AMD Phenom II X2 720 Black Edition (Deneb) 2.8 GHz, 6 MB L3 cache
|Thermalright Ultra 120 Extreme
|ASRock M3A790GXH/128M (Socket AM3) 790GX/SB750
|Western Digital VelociRaptor WD3000GLFS 300 GB 10,000 RPM SATA 3 Gb/s HDD
|Zotac GeForce GTX 260 Core 216 896 MB
|Cooler Master UCP 1100 W
|System Software and Drivers
|Microsoft Windows Vista Ultimate Edition x64 Service Pack 1
|Mainconcept Reference 1.6.1
|MPEG-2 to H.264, 28 second HDTV clip (1920x1080)
|TMPGEnc 4.0 XPress
|DivX 6.8.5, Xvid 1.2.1 Video: Terminator 3 SE DVD (720x576) 5 min. Audio: Dolby Digital, 48000 Hz, 6-channel, English
|64-bit .exe, Audio CD "Terminator II SE," 53 min., .wav to .mp3 @ 160 kbps
|Compression = Best, Benchmark: THG Workload
In Mainconcept, an extra 2 MB of cache buys a second off of the encoding job's time. But the addition of a fourth core to the X3 knocks 41 seconds off of the same task. Clearly, in applications able to take advantage of multiple cores, turning an X3 into an X4 yields more performance than getting a slightly higher overclock, for instance.
Again, we see the cache help a little bit. But the 2.8 GHz Phenom II X3 turns in better times for the latest version of Xvid due to its clock speed advantage over the X4 810. In DivX 6.8.5, the fourth core helps AMD's Phenom II X4 810 turn in better times. But a combination of four cores and an extra 200 MHz shows the unlocked X3 720 in the most favorable light.
Clock speed reigns supreme here, and LAME doesn't care about more cache or a fourth core.
WinRAR is the only application that we ran able to demonstrate the gains of an extra 2 MB of L3 cache. Because the app is also threaded, the quad-core X4 810 ends up performing close to the quicker X3 720.

Good article. Now if you can just get your ad clowns from sticking us with those annoying ads.....!Reply
test them with games... some people care about that :PReply
Well, but the point isn't the benchmarks. We already know that most games are going to be limited more by graphics horsepower versus whether a CPU has three or four cores/4MB shared L3 or 6MB shared L3.Reply
In fact, when it comes to gaming, you're going to be better off looking for the fastest overclock possible with your three good cores or 4MB of known-good cache, really.
omg you replied to me... i'm so honoured :PReply
but yes, i agree... but if you had crossfire gpus, this would make a difference. but then again, i think you'd have the money to buy the real thing (phenom II 920)
i like this article toms should do more stuff like this.Reply
Page 3 "it ran for an hour sans error before we shut it down" - mistake?Reply
Me wonders if extra v's would help both to the memory, HTT and cores etc, or underclock that extra core if possible....
On the other hand as all overclockers/modders should be aware THERE'S NO GUARANTEE on what you can get out of your hardware etc.
Out of interest, is the third core ("Core 2"... LOL) still always the culprit of every X3 (unlockable or not)?
Now if only there was some super secret on modding my Q6600 into a i7 940.....
Hey Apache! No error, sans = without.Reply
still reads wrong to me?Reply
Good article but can someone explain how ACC % works? Also, where do we start in terms of ACC % if we're tweaking for stability?Reply
cangeliniHey Apache! No error, sans = without.Reply
The only reason I know that is because of Wayne's World2.
