Test Setup
In the next few days we will publish a review of the ATI Crossfire Xpress 3200 AM2 that will compare performance of the RD580 and nForce5 chipsets. We also have several AM2 motherboard reviews in process that will compare performance and features of AM2 motherboards. This review examines the performance of an nForce 590SLI system against that of a comparable nForce4 SLI X16. We are testing equally configured systems with only the chipset and required memory being different. Our test suite consists of synthetic and actual application benchmarks.| Performance Test Configuration - Foxconn C51XEM2AA | |
| Processor: | AMD Athlon 64 X2 - 4800+ (AM2) |
| RAM: | 2 x 1GB Corsair Twin2x2048-8500C5 DDR2-800 as noted at (CL3-3-3-13) |
| Hard Drive(s): | 1 x Maxtor MaXLine III 7L300S0 300GB 7200 RPM SATA (16MB Buffer) |
| System Platform Drivers: | NVIDIA 9.34 |
| Video Cards: | 1 x EVGA 7900GTX - All Tests 2 x EVGA 7900GTX for SLI Tests |
| Video Drivers: | NVIDIA 91.27 |
| Cooling: | Zalman CNPS9500 AM2 |
| Power Supply: | OCZ GamexStream 700W |
| Operating System(s): | Windows XP Professional SP2 |
| Performance Test Configuration - Asus A8N32-SLI | |
| Processor: | AMD Athlon 64 X2 - 4800+ (S939) |
| RAM: | 2 x 1GB OCZ EB DDR PC-4000 Platnium Edition DDR-400 as noted at (CL2-2-2-7) |
| Hard Drive(s): | 1 x Maxtor MaXLine III 7L300S0 300GB 7200 RPM SATA (16MB Buffer) |
| System Platform Drivers: | NVIDIA 6.85 |
| Video Cards: | 1 x EVGA 7900GTX - All Tests 2 x EVGA 7900GTX for SLI Tests |
| Video Drivers: | NVIDIA 84.21 |
| Cooling: | Tuniq 120 |
| Power Supply: | OCZ GamexStream 700W |
| Operating System(s): | Windows XP Professional SP2 |
Our processors are both AMD X2 4800+ units, and our motherboard choices are the NVIDIA tuned and designed Foxconn C51XEM2AA for AM2 and the Asus A8N32-SLI Deluxe for S939. Our memory selections and settings represent the fastest memory we currently have available for each platform. All other components are equal with each system BIOS being set to default except for the memory timings. The driver sets are the latest release for each platform and would be the driver sets utilized if you purchased either platform today. Although this test is not an exact apples-to-apples comparison, it should provide an interesting analysis if a pending upgrade is in your future.
Memory Performance
The nForce 500 platform with DDR2 memory holds a commanding lead in memory bandwidth over the nForce4 system with DDR. However, as we have already discussed in our AM2 DDR2 versus 939 DDR Performance article, this advantage only provides performance improvement results from 0-7% in real-world benchmarks due to the fact the K8 architecture is not particularly starved for memory bandwidth. We will find in our next round of tests if these results hold true.

<quote>These devices can be configured in RAID 0, 1, 0+1, and 5 arrays. There is no support for RAID 10.</quote>That's probably because there's effectively no difference between 1+0 and 0+1 on a good controller.

Doesn't this require support from the modem/router too?
The delay (usually) happens in the modem and not in the network card.
Zoomer - Saturday, May 27, 2006 - link
No, because you make the bottleneck your network card, instead of the modem. :)There will be a slight loss of throughput. Read some QoS articles. lartc.org is also a good resource. I bet it's the same principle. ;)

take out the "to"

Thanks, it is corrected.....Googer - Wednesday, May 24, 2006 - link
When benchmarking core logic it's should be a high priority to measure I/O performance, since that is the primary job of any AMD Chipset.Where are the HDD, Network, Audio, and R.A.I.D. benchmarks?

I answered above but we will have full benchmarks in the actual motherboard articles. Our efforts in the first three days was to prove out the platform and features that were added or changed (still doing it, feels weird to be up almost 72 hours). In answer to your question-
Foxconn Board
Network-
Throughput - 942 Gb/s
CPU utilization - 14.37% (with TCP/IP offload engine on), near 30% off.
HDD/RAID
No real difference compared to nF4 as we stated. The numbers are within 1% of each other. The interesting numbers will be in our ATI SB600 comparison.
Audio-
Dependent on the codec utilized in each motherboard, the RealTek ALC883 used in most of them have the same numbers as the nF4 boards. The only difference is the new 1.37 driver set we used. It will be interesting in the comparison as Asus went back to ADI for HDA.

That's why AT is my favorite review site - 'cause you're really crazy bunch :-) Just don't ruin yourself completely, we need you!Gary Key - Wednesday, May 24, 2006 - link
The ending should read NF4 Intel or ATI/Uli AMD boards. Where is that edit function? Hit enter too soon. :)Gary Key - Wednesday, May 24, 2006 - link
They will be in our roundup comparison and ATI AM2 articles.
