MSI NX7800 GTX x 2: Retail SLI
Our Test System & 3DMark05
HOW WE CONFIGURED THE TEST SYSTEM: We tested the MSI NX7800GTX cards on a Gigabyte K8NXP-SLI nForce 4 SLI chipset based motherboard, powered by an AMD Athlon 64 FX-55 processor and 1GB of low-latency Corsair XMS RAM. The first thing we did when configuring this test system was enter the BIOS and loaded the "High Performance Defaults." The hard drive was then formatted, and Windows XP Professional with SP2 was installed. When the installation was complete, we installed the latest nForce 4 chipset drivers, installed all of the other necessary drivers for the rest of our components, and removed Windows Messenger from the system. Auto-Updating and System Restore were then disabled, the hard drive was defragmented, and a 768MB permanent page file was created on the same partition as the Windows installation. Lastly, we set Windows XP's Visual Effects to "best performance," installed all of the benchmarking software, and ran the tests.

;) 3DMark05 |
3DMark05 is the latest installment in a long line of synthetic 3D graphics benchmarks, dating back to late 1998. 3DMark2005 is a synthetic benchmark that requires a DirectX 9.0 compliant video card, with support for Pixel Shaders 2.0 or higher, to render all of the various modules that comprise the suite. To generate its final "score", 3DMark05 runs three different simulated game tests and uses each test's framerate in the final tabulation. Fillrate, Memory bandwidth, and compute performance especially all have a measurable impact on performance in this benchmark. We ran 3DMark05's default test (1,024 x 768) on all of the cards and configurations we tested, and have the overall results posted for you below. |
With identical clock speeds to NVIDIA's reference GeForce 7800 GTX cards, the MSI NX7800GTXs, whether in a single card configuration or running in SLI mode, understandably performed at nearly identical levels. In a single card configuration, the MSI NX7800GTX just barely squeeked by NVIDIA's reference GTX. When running in SLI mode, however, the MSI cards finished just shy of the reference cards. In SLI mode, NVIDIA's reference GeForce 7800 GTX cards finished the 3DMark05 default test 56 points ahead of the MSI cards.
