Pre-release Tests Conducted on AMD Deneb

AMD Deneb is the code-name for the 45nm quad-core CPU which AMD plans to release soon. Chinese website ITOCP got their hands on two engineering samples. They used these samples at various clock-speeds set by altering the FSB multiplier and Vcore voltage. These chips were then subjected to rounds of Super Pi 1M benchmark. The results look rather luke-warm compared to what we saw of the Intel Bloomfield chips recently. The Deneb CPUs were supported by an AMD RD790 motherboard and 2 GB of DDR2 800 MHz unganged memory, running at timings of 5-5-5-18. The Phenom X4 Deneb 45nm will feature 6 MB of L3 cache apart from the usual 512 KB L2 caches dedicated to the cores.

As of today, AMD is close to over a year and a half behind Intel with the implementation of the DDR3 system memory standard, and it doesn't look like we are going to see a DDR3 AMD platform only until late this year or early next year. Chilian website CHW.net published slides of the roadmaps for AMD chipsets in the months to come, also published are slides refering to the details of the next generation southbridge by AMD, even though the latest entry, the SB700 is only teething and only the latest motherboards with 7-Series chipsets feature this.

Regardless of theoretical performance, the upcoming AMD RD790 and Athlon 64 Black Edition line of processors certainly are overclockable and feature-laden. On nothing but air cooling, MSI testers were able to get an RD790 chipset to a remarkable 510MHz FSB speed. Once the RD790 is released with PCI Express 2, CrossFire X, and support for goodies such as Phenom, we will see one seriously good platform.

There has been a lot of hype surrounding both the AMD Phenom X4 and the AMD RD790. Testers combined both, violated a couple NDAs, and pitted them against current offerings from Intel in one of the most stressing games of all time: Crysis. The chart, if true, speaks for itself...

While Intel is preparing to move on to a 45nm micro-architecture, AMD is preparing true quad-core processors, and working on a quad-graphics card solution. The technology that will allow for four graphics cards to be stuck in one system will be called "QuadFire", and there are no major details out at this time, other than the name and pictures of supporting motherboards. The chipset supporting "QuadFire" is AMD's own RD790, which is pictured below in MSI's K9A2 motherboard. The RD790 is designed to work with a Phenom processor, has six SATA ports, and two E-SATA ports.
