Test Setup and 3DMark05


HOW WE CONFIGURED THE TEST SYSTEM: We tested the Gigabyte GV-NX78T256V-B on an ASUS P5N32-SLI nForce 4 Intel Edition SLI X16 chipset-based motherboard, powered by an Intel Pentium 4 550 processor and 1GB of low-latency Corsair XMS2 DDR2 memory. 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 1536 MB permanent page file was created on the same partition as the Windows installation. Lastly, we set Windows' Visual Effects to "best performance," installed all of the benchmarking software, and ran the tests.

Performance Comparisons with 3DMark05 v1.2.0

3DMark05 is the latest installment in a line of synthetic 3D graphics benchmarks from Futuremark Corp that date back to late 1998.  The benchmark itself isn't based on a playable game engine, but it does boast fairly impressive DX9-driven visuals and lighting effects.  It's also a versatile DirectX 9 benchmarking tool that we feel is relative in terms of presenting our readers a full performance profile for 3D graphics and host processors. It's not a metric that you can exclusively gauge real-world performance on but rather a complement to our entire suite of application-based testing.  We ran 3DMark05's default test (1,024 x 768) on all of the cards and configurations we tested.

As you can easily see in the scores above, the Gigabyte GV-NX78T256V-B easily outperformed not only the older MSI NX6800GT, but picked up an extra 10% over ATi's X850XT as well.  It's a clear indication of how well the additional pipelines of the 7800GT (20) prevent it from getting bogged down like the X850XT or 6800GT (16 pipes each).  The X850XT is even clocked higher on both core and memory speeds, but still can't quite compete in this synthetic benchmark.
