Radeon HD 7990 And GeForce GTX 690: Bring Out The Big Guns
EVGA recently lent our German lab one of the GeForce GTX 690s we've had in the U.S. for months. The purpose? To pit against HIS' upcoming 7970 X2 and PowerColor's Devil13 HD7990, both dual-Tahiti boards vying to become the world's fastest graphics card.
Benchmark System
We first benchmarked all the graphics cards in our VGA 2012 benchmark system. After that, we took a look at installation and operation in a closed case.
Benchmark System | |
---|---|
CPU | Intel Core i7-2600K (Sandy Bridge), 32 nm, 4C/8T, 8 MB Shared L3 Cache, Hyper-Threading Enabled, Overclocked to 4.5 GHz |
Motherboard | Gigabyte Z68X-UD7-B3, Intel Z68 Express, BIOS F10 |
Memory | 4 x 4 GB Kingston HyperX DDR3-1600 |
CPU Cooler | Cooler Master TPC 800 with Noiseblocker eLoop B12-PS (PWM) |
SSD | Kingston V200+ 480 GB |
Power Supply | Corsair AX1200i Digital ATX Power Supply, 1200 W, 80 PLUS Platinum |
Operating System | Windows 7 x64 Ultimate |
Driver | Catalyst 12.11 (Beta) and Catalyst 12.9 GeForce 306.97 WHQL |
Temperature | 22 °C (held constant) |
Closed Benchmark Case | NZXT Phantom 820 |
We're particularly interested to compare the performance of AMD's Catalyst 12.9 driver package to the more recently-released 12.11 beta driver, which the company claims should be much faster in a number of games.
Unlike many of the graphics card reviews you read, we're conducting our testing today in a closed chassis. After all, it can't be that easy to dissipate more than 500 W worth of heat, and we want to know what effect that has on real-world thermals and acoustics.
