Overclocked AMD FX 8150 Review : Part I, Enter Gigabyte

PART I of V : Return of AMD FX, Enter Gigabyte

My System:

AMD FX 8150 @ 4.90 Ghz
Promilatech Genesis Cooler - 3 x 135mm Scythe Kama Flex 100CFM fans
Maingear T1000 TIM
8 Gb DDR3 Team Xtreem 2400 cl9 @  @ 1987 Mhz / CL9
Gigabyte GA-990FXA-UD7
XFX HD 6990 + Accelero Twin Turbo Cooler @ 990/1500 Mhz
RevoDrive 3 x2 - 240 Gb 

Comparison Systems : 

AMD FX 8150 @ 4.81 Ghz
Promilatech Genesis Cooler - 3 x 135mm Scythe Kama Flex 100CFM fans
Indigo Xtreme TIM
G. Skill 2200 cl7 @ x 2190 Mhz / CL10
ASUS Crosshair V
XFX HD 6990 + Accelero Twin Turbo Cooler @ 990/1500 Mhz

Intel i7 3770k @ 4.7-4.9Ghz
Various 4-16 Gb DDR3
Various Z77 Motherboards
Various GPUs

We see that for the benchmarks used in Part I of my review, FX only falls signficantly behind when only a single thread is used. When only one core is being used we see a 25-40% benefit per Ghz for the 3770k over the FX 8150.

When all threads can be used, Bulldozer does a good job of making up for the lost single threaded performance. Scaling for FX outshines the i7 3770k by a significant margin.  Most notably with techarp's x264 HD, where my FX 8150 @ 4.9 Ghz beats a 5.0 Ghz 2600k, and narrowly loses to a 4.9 Ghz 3770k. (Check source 19)

In TrueCrypt 7.1a we see a 4.9 Ghz FX 8150 performing slightly better than its 22nm 3770k intel counterpart at 4.7 Ghz.

In 7-Zip we see the FX 8150 jumping 2.7 % percent ahead of its 3770k counterpart at the same 4.9 Ghz clock for Compression, but falling behind 2.7% with decompression.

The temperature of a 3770k is also seen to sky-rocket up to 78C during a SuperPi 32m test, while my FX 8150 doest hit above 59C.

Next week well see how my GPU  handles graphically intensive workloads on my new Gigabyte board.

Stay Tuned!


  1. I appreciate everything you are doing in the name of fair comparisons and benchmarks! Keep up the good work.

  2. Thanks for the feedback!

  3. Can't wait for Piledriver! If only the FX-8150 could offer the same performance at a reasonable power consumption ...

  4. With 15-25% higher IPC, vishera will close the gap with the consumer i7 3770k especially given its lower power and higher clocks.

  5. How's your LLC setting on your UD7?
    My UD3 has some killer vboost with LLC on Extreme (according to Hardware monitor, from 1,45v to 1,58v)
