Three new Xeons added to the Q4 launch lineup

Intel’s latest roadmap reveals three new Penryn based Xeon models with a higher front-side bus speed – 1600 MHz. The three new 1600 MHz front-side bus processors are available in dual-core and quad-core models. Quad-core Xeon E5472 and E5462 are the first quad-core models to receive the 1600 MHz front-side bus treatment.

The Xeon E5472 features a 3.0 GHz clock speed while the E5462 features a 2.8 GHz clock speed. These models feature 80-watt thermal ratings as designated with the E moniker. Intel plans to release these 1600 MHz front-side bus processors in Q4 2007 with the rest of the Penryn family.

Pricing for the 1600 MHz front-side bus processor starts at $797 for the E5462 and $958 for the E5472, per processor, in 1,000 unit quantities. As far as pricing goes, the Xeon E5472 slots below the 3.16 GHz X5460 while the E5462 slots below the 3.0 GHz, E5450.

Intel has one 1600 MHz dual-core Penryn based Xeon processor ready for launch – the E5272. The Xeon E5272 features a 3.4 GHz clock speed and is priced at $1,172. Intel has also pulled in the launch of all dual-core Xeon processors to Q4 2007, with the quad-core processors. The dual-core Xeon E5260 and E5205 will also launch in Q4, not the Q1 2008 date earlier roadmaps showed.

Intel 1600 MHz front-side bus Xeon processors will drop into the upcoming Seaburg chipset. Seaburg features support for dual PCIe 2.0 x16 slots and up to 128GB of memory.

Yorkfield at 3.0 GHz scores 26,000

From the inq article -
Agena FX 2.5GHz scores 23,768
Agena FX 3.0GHz scores 30,031

That’s a big difference; there have been rumors about Agena/Barcelona coming good above 2.6GHz. However the article doesn't give enough info, how did they get from 2.5 -> 3.0 GHz? Was the system overclocked, or the processor swapped? At 2.5GHz were the X2900s overclocked or was that only done on the 3.0GHz system?

The RD790 runs PCIe 2.0, AMD have said that X2900 series supports PCIe 2.0, is any of the improvement due to fiddling with PCIe settings or overclocking the FSB/HTT to lower the latency of the PCIe?

The article says that two X2900s were used but then on subsequent questioning the author can't say if there are three X2900s used (WTF?), it is a possibility as AMD have said that the RD790 will have 3 PCIe x 16 sockets. Again we don't know what they are electrically yet (Bandwidth may be restricted on one if it 'only' helping with physics as was originally planned i.e. x4 or x8, therefore using three may not drastically increase the score).
