Hi, first off I would like to introduce myself. My name is Panos, and I am a computer enthusiast who loves to benchmark. I am new to the blog scene, but I hope you guys like it here.

My first goal is to finally get some AMD FX 8150 benchmarks at a decent overclock. I have noticed that many websites, except for overclockersclub.com, really have not pushed FX to its limits. On top of that, poor FX is always paired with a more lower end card! Remember how AMD recommended using a 6990 with the FX 8150 in their original FX promotional video?

Enter Scorpius,

My Gaming Rig - ON AIR!!

AMD FX 8150 @ 4.81 Ghz 24/7 Stable (23.5 x 204)
Promlatech Genesis - 3 x Scythe Sflex 135mm
G.Skill 2200 Mhz Cl7 DDR3
XFX 6990 stock (830/1250) > OC (990/1500) 2 Hr Stable (Ungine Heaven 2.5) Catalyst 12.1 Preview
Arctic Twin Turbo 6990 Cooler
OCZ Revodrive 3 X2 240 Gb
HAF 932 - 10 x Additional Scythe Fans
OCZ 1000w ZX Gold PSU

Benchmarks:

Ungine Heaven 2.5
3DMark11 P/X
AID64
7Zip
Winrar
Passmark
SiSoftware Sandra 2012
PCMark 7
Cinebench 11.5
Cinebench 10

Possibly more

Games:

Dirt 3
Alien vs. Predator

Possibly more

Finally Bulldozer can Breath! Will FX shine? or will it fall short? Will an overclocked FX bottleneck a 6990 OC'd?

Well,

First results ARE IN!! Techarp H.264 first and second pass results are up.


Tech ARP H.264 encoding benchmarks!! FX is back!

ROUND1 :

Tech ARP H.264 encoding First Pass / Second Pass Results


TEST SYSTEM:

AMD FX 8150 @ 4.81 Ghz 24/7 Stable (23.5 x 204)
Promlatech Genesis - 3 x Scythe Sflex 135mm
G.Skill 2200 Mhz Cl7 DDR3
XFX 6990 stock (830/1250) > OC (990/1500) 2 Hr Stable (Ungine Heaven 2.5) Catalyst 12.1 Preview
Arctic Twin Turbo 6990 Cooler
OCZ Revodrive 3 X2 240 Gb
HAF 932 - 10 x Additional Scythe Fans
OCZ 1000w ZX Gold PSU



THE RESULTS:


First Pass Results (Single Core Performance) :




In this benchmark, the single core performance of an overclocked AMD FX 8150 CPU @ 4.8 Ghz is better than a 3.7 Ghz (tubro) i5 2500k, but worse than a 4.0 Ghz i5 2500k.

Second Pass Results (Multi-threaded Performance) :



When all cores are used FX shines! Performance is well over a i7 2600k @ 4.5 Ghz, but less than 2 fps shy of a i7 2600k @ 5.0 Ghz. I am not sure about the low 5.18 ghz 2600k score =S... but its well over that aswell. It should also be notes that 3960x at 3.8 Ghz Turbo is not much faster than a 4.8 Ghz FX 8150.

This benchmark is well designed to take advantage of Bulldozer's architecture, but what about others?

3DMark11 Performance / Extreme Performance



ROUND 2 : 3DMark11



Finally a benchmark that utilizes GPU! We will see here whether FX bottlenecks or not while overclocked to 4.8 Ghz. The score to really look at is GPU score (as this directly relates to fps of the rendered scenes), but because the total score also heavily relies on GPU score (especially in the Extreme Preset) it is also a good measure.


RESULTS:


3DMark11 Performance Preset:

AMD FX 8150 @ 4.8 Ghz
6990 OC @ 990/1500 Mhz




Compared Results (with several 6990 OC's) :




As you can see the graphics score of my OC'd 6990 does not fall systematically behind intel rigs with similar GPU OC's. My GPU Score of 12046 is a clear winner over the rest of the rigs tested., however with combined and physics scores also put into consideration FX falls behind with a total score of only 10318.

The most noted comparison is that with the i5 2500k at 5.35 Ghz with a 6990 @ 1000/1420. Although it manages to squeeze out slightly higher combines/physics score, it still seems to bottleneck in GPU scores. The only intel cpu coming close to FX GPU score is the 3960x.

It should be noted that the OC on the 6990 does play a role in GPU score, so take these results with a grain of salt. a 930 Mhz OC is still 7% below a 990 Mhz OC, but nevertheless we can determine that FX does not heavily bottleneck when it is overclocked to 4.8 Ghz. What about Extreme Preset?

3DMark11 Extreme Preset:

AMD FX 8150 @ 4.8 Ghz
6990 OC1 @ 880/1250Mhz
6990 OC2 @ 990/1500 Mhz

- - - OC1 - - - 6990 @ 880/1250Mhz




- - - OC2- - - 6990 @ 990/1500 Mhz




Comparison (from Hexus.net) :


- - - OC1/OC2 - - -





The most noteable comparison is between my stock 6990 @ 880/1250 paired with my AMD FX 8150 @ 4.8 Ghz, and their stock 6990 with the exact same clocks paired with a 980x @ 3.6 Ghz Turbo. The difference in score is mostly due to a difference in Graphics Score, as the 980x generally destroys the FX in physics and combined results even at stock.


This tells us alot about where FX bottlenecks or not, and the answer seems to be NO, atleast when comparing to a 980x @ 3.6 Ghz. The difference in score is roughly 5%, where the FX is slightly favoured.


When my 6990 is pushed to its stable limits @ 990/1500 Mhz, my score jumps an additional 13%. That is, for a 12/20% (clock/memory) overclock on my 6990. It is clear that an AMD FX 8150 does not bottleneck on Extreme Preset.


Look here : http://amdfx.blogspot.com/2012/01/look-at-this.html for comparisons to 1100t @ 4.2 Ghz and i7 2600k Stock @ 3.8 Turbo.






These are examples where their GPUS are being bottlenecked. My Stock OC1 (880/1250) Graphics score actually manages to beat a 6990 @ 950/1450 on an 1100t @ 4.2 Ghz. (meaning higher fps). Here is an example where OCing a 6990 will not result in much benefit. (ie. the bottleneck is around that CPU frequency)


It is also interesting to see that OC'd my 6990 is the clear winner against the 980x @ 3.6 Ghz 580 SLI @ stock in the Extreme Preset.


It should be noted that the drivers I used were Catalyst 12.1 beta drivers, and those used in the HEXUS test were 11.4. The difference in 3DMark 11 scores should be negligible however. Also the 3DMark11 version used for my Performance Preset Results is 1.03, while that of the Extreme Preset Results is 1.02.

If a HD6970 or GTX580 is a low end card then I don't want to know what high end is. Thats what most reviews I have seen have it paired with.

On top of that, not everyone can afford a $700+ card (Newegg only has a Gigabyte one for a nice $739 w/free shipping). So AMDs advice, while strange, is only to try and market their platform to you as a consumer, not because you will get the best performance just because you pair it with their largest money grabbing GPU.

Honestly I am afraid to know the price of the HD7990 if the HD7970 is going to enter at $550ish this month. Probably near $800-$1K.

That said, I would make sure you do the tests a few times to verify results. There are always little factors that can change things around. When I got my HD5870 I did the VALVe CS:S and HL2 LC benchmarks 3 or 4 times to compare to my HD4870. Of course I got close to 2x the FPS but still make sure you doule or even triple check your numbers.

For gaming though, I doubt anything will change much. Most games these days are heavily GPU dependant so the CPU is normally out of the picture for the most part.

As for the return of FX, I will agree when it can live up to the original FX name, which was first tarnished by the Quad FX setup, and by that I mean beat the pants off of an Intel equivalent while using less power and staying around the same price.

BTW, on your blog you have scores down but you are doing the Intel scores at stock and the AMD ones are mostly overclocked. Not a fair comparison TBH. Don't let anything cloud your judgement or cherry pick to make what you would prefer look better. Thats a bad sign to start that way.

I agree with Jimmy, Stock vs Stock, or max OC vs max OC, but not OC vs Stock.

And 10 fans in the HAF, i'll remember to let you lip read should we meet face to face.

First results ARE IN!! Techarp H.264 first and second pass results are up.

My voltages range between 1.428-1.440V at 4.81 Ghz. I will post my idle and stress temps aswell as a cpu-z screen later today!! =)

STAY TUNED,

Tomorrow 3DMark 11 scores! Will FX fail to keep up with Sandy Bridge? Will my highly overclocked 6990 bottleneck?

STAY TUNED!!

Now you can compare to ALL scores , stock and overclocked, for both single and multithreaded performance!!

I was simply giving some examples.
