DFI 748-AL: First Look at SiS 748

Performance Test Configuration

Performance Test Configuration
Processor(s):	AMD Athlon XP 3200+ (400MHz FSB)
RAM:	2 x 256MB Corsair PC3200 TwinX LL (v1.1 or 1.2) Modules (SPD rated)
Hard Drive(s):	Maxtor 120GB 7200 RPM (8MB Buffer) Western Digital 120GB 7200 RPM Special Edition (8MB Buffer)
Video AGP & IDE Bus Master Drivers:	SiS AGP r1.16 & SiS IDE r2.04 NVIDIA nForce version 2.03 (1/30/03) VIA 4in1 Hyperion 4.47 (May 20, 2003)
Video Card(s):	ATI Radeon 9800 PRO 128MB (AGP 8X)
Video Drivers:	ATI Catalyst 3.6
Operating System(s):	Windows XP Professional SP1
Motherboards:	DFI 748-AL (SiS748)@200.45MHz FSB Asus A7V600 (KT600)@200.0 MHz FSB Soltek NV400-L64 (nForce2 400 SC)@ 200.5MHz FSB DFI NFII Ultra LANParty (nForce2 Ultra 400) @ 201.35 MHz FSB Gigabyte 7VT600 1394 (KT600) @ 202.78MHz FSB Gigabyte 7NNXP (nForce2 Ultra 400) @ 202.77MHz FSB Epox 8KRA2+ (KT600)@202.44MHz FSB

All performance tests run on nForce2 400 (SC)/nForce2 Ultra 400 (DC) motherboards utilized two 256MB Corsair TwinX LL PC3200 (v1.1 or 1.2) modules set to SPD timings in DDR400 mode. Dual-Channel mode was used on nForce2 Ultra 400 boards, and 2 dimms working as Single-Channel were used on the nForce2 400 Soltek NV400-L64 board.

All performance tests that ran on the KT600-based motherboards used two 256MB Corsair TwinX LL PC3200 (v1.1 or 1.2) Corsair modules in DDR400 mode. KT600 memory timings did vary slightly among the motherboards, with the Asus A7V600 requiring a Ras-to-Cas of 3 for stable operation and other KT600 boards requiring a Ras-to-Cas setting of 2. 4-bank interleave and the highest available timing option (Turbo or Ultra) was used.

Performance tests were run with the ATI 9800 PRO 128MB video card with AGP Aperture set to 128MB with Fast Write enabled. The ATI 9800 PRO is the new AnandTech video card standard for reviews.

Additions to Performance Tests

Benchmark testing is dynamic, and we have added several new benchmarks to our standard Test Suite.

1) ZD Labs Internet Content Creation Winstone 2003 — This benchmark has just been updated by ZD Labs and includes many new features in the Benchmark Suite, such as Media Encoding. It also uses the most up-to-date versions of Multimedia Creation software, which is rapidly changing as new software tools are released.

2) ZD Labs Business Winstone 2002 — ZD Labs Business Winstone has been around for many years and is a widely quoted Benchmark for measuring system performance. It basically provides a similar benchmarking suite to Sysmark 2002 Office Productivity.

3) Gun Metal DirectX Benchmark 2 — This demo/benchmark from Yeti Labs is one of the first DX9 game-based benchmarks available. Unlike some older benchmarks, such as Quake 3 that generate insane FPS ratings in the 300’s, we see performance numbers in the 30 to 40FPS range with current DX9 cards.

To give AnandTech readers a feel for how some of the newer benchmarks compare to the more familiar benchmarks used in past reviews, we have posted results for both the new benchmarks and Sysmark 2002, and all the games that have been a part of our standard benchmark suite.

New Hardware

With the release of DirectX 9 late in 2002, the availability of Benchmarks to test DX9, and the availability of DX9-supporting video cards from both nVidia and ATI, we are now using the ATI Radeon 9800 PRO for all hardware reviews.
