SiS 645: Pentium 4 DDR - Take II

3D Rendering & Animation Performance

For our readers that dabble in the professional 3D realm, here we have a breakdown of the six viewsets that make up SPECviewperf 6.1.2. For more information on exactly what each viewset simulates click here.

3D Rendering & Animation Performance SPECviewperf 6.1.2 - AWadvs-04 SiS 645 (DDR333) Intel 850 (PC800) VIA P4X266 (DDR266) SiS 645 (DDR266) 79.3 72.9 72.8 71.9 | 0 | 16 | 32 | 48 | 63 | 79 | 95

The most interesting thing here is that there is actually a decent sized lead by the DDR333 equipped SiS 645 over the competition (8%). Memory bandwidth dependencies couldn't be the explanation here since that would mean that the Intel 850 chipset would have to be at the top of the charts. The only other thing that comes to mind is a somehow superior AGP controller.

3D Rendering & Animation Performance SPECviewperf 6.1.2 - DRV-07 SiS 645 (DDR333) Intel 850 (PC800) SiS 645 (DDR266) VIA P4X266 (DDR266) 21.5 21.4 19.8 18.9 | 0 | 4 | 9 | 13 | 17 | 22 | 26

With DDR333 SDRAM the SiS 645 is able to offer performance rivaled only by the Intel 850 here; assuming close to a 14% lead over the VIA P4X266.

3D Rendering & Animation Performance SPECviewperf 6.1.2 - DX-06 SiS 645 (DDR333) Intel 850 (PC800) SiS 645 (DDR266) VIA P4X266 (DDR266) 38.9 38.9 36.7 26.8 | 0 | 8 | 16 | 23 | 31 | 39 | 47

The P4X266 has some serious issues in the Data Explorer viewset as it is clearly outperformed by the competition. Even when equipped with DDR266 SDRAM the SiS 645 outperforms it by close to 37%.

3D Rendering & Animation Performance SPECviewperf 6.1.2 - Light-04 SiS 645 (DDR333) Intel 850 (PC800) SiS 645 (DDR266) VIA P4X266 (DDR266) 9.9 9.9 9.6 7.2 | 0 | 2 | 4 | 6 | 8 | 10 | 12

Again we see more performance issues from the P4X266 in this test; it could very well be the Shuttle board being tested since we didn't see these types of issues when we looked at VIA's reference P4X266 board.

3D Rendering & Animation Performance SPECviewperf 6.1.2 - MedMCAD-01 SiS 645 (DDR333) Intel 850 (PC800) SiS 645 (DDR266) VIA P4X266 (DDR266) 34.9 34.0 32.9 31.6 | 0 | 7 | 14 | 21 | 28 | 35 | 42

While not doing as badly as it did in the earlier tests, the P4X266 still finds itself at the bottom of the charts and the 645 with DDR333 SDRAM holds a 10% advantage. When paired with the same DDR266 SDRAM, the advantage is more than cut in half and reduced to 4%.
