Overclocking performance

Overclocking

Overclocking

Maximum overclock data was added to Performance graphs beginning with the nForce4 SLI roundup several months ago. The overclocking performance graphs should allow for better comparison of the overclocking capabilities of tested boards. For more details on the specific overclocking abilities of a specific board, please refer to the Overclocking and Memory Stress Test section of individual board reviews. These charts illustrate a comparison to both Intel nForce4 boards as well as 955X based boards. As clearly as can be discerned, the ABIT was the poorest Front Side Bus overclocker of all current C19 and 955x based boards tested here at AnandTech.

Disk Controller Performance

HD Tach
(version 3.0.1.0)
MCP-04 controller Silicon Image 3132
Random Access Time 9.1ms 8.9ms
Read Speed average 50.3 MB/s 50.2 MB/s
Read Burst Speed 100.2 MB/s 99.5 MB/s

In our testing of both the MCP-04 and Silicon Image 3132 SATAII controllers, the 3132 has the slight edge in Random Access Time whereas the native MCP-04 has a slight advantage in the Read Speed and Read Burst Speed categories. With the WD 36GB 10,000 RPM Raptor controlled by either solution, this board provided very quick load times and system boot-up.

    The graphs give a nice overview, good work.

    Please consider to include the information what AF level was used into the graphs. This is something all recent reviews here have have been lacking.

    About the image quality: The shimmering was greatly reduced with the fixed driver (78.03). So it's down to NV40 level now. But 3dCenter.de[1] and Computerbase.de conclude that only enabling "high quality" in the Forceware brings comparable image quality to "A.I. low". Perhaps you find the time to explore this issue in the image quality tests.

    This article is about the unfixed quality. But to judge the G70 today, have a look at the 6800U videos.

    This article shows the performance hit of enabling "high quality"

    oops wrong forum

    Thanks for the clarification Wesley, and welcome aboard Randi!
  • Wesley Fink - Friday, October 7, 2005 - link

    Please welcome Randi Sica as our newest reviewer at AnandTech. Randi is a friend who is well known in the Extreme Overclocking community as Mr. Icee. That gives Randi a keen eye when looking at what's right and wrong with a motherboard from an Extreme Overclocker's perspective.

    We think you will also find Randi's review perspective and approach a little different. Those who have been screaming for overclocked benchmarks in board reviews will find them in Randi's reviews.

    This is Randi's first review at AnandTech, so please make him feel welcomed.

    PASSIVELY COOLED! That's soooo appealing. I wish board makers could get the northbridges cool enough on the AMD chipset to make more passively cooled boards. I hate having another fan in the case, especially a tiny one running at high revs making a racket. It's bad enough most GPUs suffer from that, we don't need another one on the mobo. :(

    Correct me if I'm wrong here, but I don't think the audio is on the PCI-E bus. The codec hangs directly off the southbridge, and isn't on any bus. If you look at the slot the audio card goes in, it's actually a PCI-E 1x connector turned backwards. I'm assuming that they use that particular connector because it's cheaper than designing something custom. Still, not a bad job on the CPU utilization.

    BTW, the chip is an ALC850, not ACL850 as mentioned on page 3.

    Thanks for pointing this out. The references to the audio connector have been corrected to "dedicated audio connector" which it is unless we hear otherwise from Abit. We have seen the separate dedicated audio card can significantly reduce CPU overhead, and Abit seems to have done well with this idea on this board.

    The superior Workstation performance demonstrated here involves two parts: the ABIT NI8 SLI coupled to the D840 EE Dual core P4. The other boards compared here feature a standard single core solution


    Wait, what? You are comparing a dual core HT enabled system with several other Intel systems using only a single core? How is this apples to apples? This makes all of the benchmarks you did worthless.
  • Wesley Fink - Friday, October 7, 2005 - link

    ALL tests used the exact same CPU except the Workstation test results. That means general performance, encoding, DX9, and DX8 gaming were tested on all reported platforms with the Pentium D 840EE.

    The Workstation Tests were included because they were an interesting picture of a 3.6GHz single core being soundly outperformed by a 3.2GHz dual-core Pentium D. The workstation tests were meant to be an illustration, not a direct comparison.

    The 3.46EE was used in some past memory tests to achieve high memory bus speeds, and the reference was only made in examing overclocked memory FSB speed records - not comparative performance.

    We will make this clearer in the review, but all of the benchmarks except Worksation are definitely apples to apples tests - even down to HT being enabled in all tests.
