| AMD's Phenom Processor - Beyond Erratum 298 | |
|
(Author: Michael Schuette, January 1, 2008) |
The Spider Platform
The Spider platform is built around AMD’s 700 series chipset featuring three distinct chips with full or reduced feature sets, namely the 790FX, the 790X and the 770 chipset, with the latter lacking CrossFire capabilities.
In short, here are a few technical specs of the platform:
| HyperTransport™ 3.0 technology | More than doubles the CPU communications bandwidth to graphics as compared to HT1. |
| Auto Xpress* | The technology for qualified performance boosts that automatically activates with AMD/ATI components to deliver better CPU, GPU, and system performance
|
| PCI Express® Generation 2.0 | Doubles the graphics bandwidth over earlier PCI Express. |
| GPU-Plex Technology | Scalable twin-engine technology on a single chip enables flexible configurations for multiple graphics cards on a single x16 link. |
| Quad PCIE Blocks | Native PCI-E cores on one chip allow for fast GPU to GPU communications by eliminating the latency and possible bandwidth issues of multiple PCIE chip designs. Double pumped with Xpress Route for fast Core to Core transfers. |
| ATI CrossFireX™ Technology: | Scalable graphics performance with a widely certified infrastructure. |
| Backwards compatibility | Supports all AM2 pinout-compatible CPUs |
| AMD OverDrive™ | Out of the box overclocking and system optimization utility necessary to mitigate the performance issues caused by patching the BIOS for the bug described in Erratum 298 |
| AMD RAIDXpert | RAID setup configuration utility to allow access from remote locations. |
Motherboard Support and Launch Partners
Launch partners currently include ASUS, ASROCK, Sapphire, Gigabyte, MSI, ABIT, DFI, Foxconn, Jetway and there will be motherboards from all vendors trickling into the market place in due time. For the article at hand, we are exclusively using the ASUS M3A32-MVP with the 0603 BIOS. We ran earlier BIOS versions, including the -11151, which scored higher for example in raw memory bandwidth but lagged in applications. Our choice was based on the notion that for all practical purposes application performance may be more critical than raw bandwidth. We also ran several different versions of AOD starting from 2.09 but settled on the latest beta 2.13 for overall best performance, compatibility and reliability.
