SiSoft Sandra 2011 Benchmarks

In our benchmark tests, we will be comparing Gigabyte X79-UD7 to the SABERTOOTH 990FX and to a similarly configured Intel Core i5 system running on Gigabyte Z68X-UD7-B3 mainboard.

The Gigabyte X79-UD7 is paired with INTEL Core i7 3960X,  ASUS Radeon HD 6850 with Catalyst 11.11, 4 x 2GB DDR3-2133 Corsair memory at C9-11-10-27-98-1T, Kingston SSDNOW V Series 64GB and runs Windows 7 Ultimate 32 bits.

The Gigabyte Z68X-UD7-B3 with Core i5 2500K runs at 100.3×33 (3.309GHz) while the ASUS SABERTOOTH 990FX with Phenom II X6 1100T has it’s CPU clocking at 200.7×16.5 (3.3115GHz).

The same 4GB RAM, graphics card (ASUS Radeon HD6850+CAT 11.5) is used on the two boards. The ASUS SABERTOOTH is configured to run at C7-8-7-20-1T DDR3-1600 whereas the Intel Z68 runs at DDR3-1866, C7-8-7-20-1T.

The processor used on the SABERTOOTH 990FX is a Phenom II X6 1100T processor clock at 200.7MHz x 16.5. On the Intel Z68, we have a Core i5-2500K processor running at 100.3 x 33.

We will first test out the memory benchmarks, followed by Arithmetic, Multimedia and Transcoding.

In Memory benchmark, we see a big improvement in memory bandwidth as X79 adopts a quad channel architecture. In fact, with the 4 modules running at DDR3-2133 as compared to the two other boards at dual channel DDR3-1866 (C7) and DDR3-1600 (C7), we aren’t a bit surprised by the result. The memory bandwidth broke the 40GB/s mark reaching 46.15GB/s

Although the three processors are clocked at almost 3.3GHz, we can see from the scores show otherwise. With the Core i7-3960X on X79-UD7, the processor arithmetic score doubled to 143.36 GOPs. That is 2.13X faster than the Phenom II X6 1100T scoring only 67 GOPs and Core i5 2500K at 59.48 GOPs.

What about in multimedia tests ? The Gigabyte X79-UD7 with the Core i7-3960X scored 225 Mpix/s as compared to the 81.14 and 95.69 on the AMD 990FX (with Phenom II 1100T) and Intel Z68 (with Core i5 2500K).

The same can be said with the transcoding test. The Gigabyte x79-UD7 paired with the 3960X is almost 1.3X faster than the 2500K
