Intel (NASDAQ:INTC) just unveiled its latest server CPUs. The 8-core Intel Xeon E5-2600 series -- codenamed Jaketown -- are the ultimate Sandy Bridge parts. In IT Blogwatch, bloggers crunch the numbers.

: Your humble blogwatcher curated these bloggy bits for your entertainment. Not to mention: Disturbing wedding dress imagery... Agam Shah reports:
The processors include up to 8 cores...are up to 80 percent faster...[and] consume half the power of their predecessors, Intel said. ... Intel has over 400 server designs with the new chip, [it] said. ... IBM claimed its new two-socket BladeCenter HS23 is 62 percent faster...than its predecessor. Simon Sharwood adds:
Intel has built bandwidth improvements...to cut latency by 30 percent, which could help scale cloud deployments and...more virtual machines. ... [It's] the first to integrate the PCI-Express 3.0 bus on the processor...to transfer data between components...at 8 gigatransfers per second. ... [It's] also the first...to route I/O traffic directly to processor cache...reducing latency and saving power.
Stefan Gillard, CEO of outsourced digital production facility Studio Engine...(Harry Potter and the Deathly Hallows and Happy Feet Two)...reported the E5 delivers in terms of speed. ... The new silicon blew them away, achieving a Passmark score of over 30,000. Bob McMillan notes the secret supers:
But Gillard also had troubles with heat...he cannot imagine...that a [blade] rack with specs [to him] will be comfortably cooled. He nonetheless declared the E5 a great product.
Intel has been testing out early samples of the chip...for months now. Last fall, [they] were already inside inside 10 of the high-performance systems listed on the Top500...most powerful supercomputers. Chris Angelini says it's the ultimate Sandy Bridge part:
The supercomputer geeks like the new processors because they use a new...Advanced Vector Extension (AVX) that doubles the speed of...operations that are commonly done by scientific simulation, financial analysis, or media software. ... In tests, the X5 systems were much faster...because Intel has built I/O processing directly into the chip. ... The chips also speed up encryption, thanks to Intel [AES extensions].
Intel neutered all of [the] desktop-oriented processors to some degreewhether to hit certain power targets...or more easily differentiate its server parts, we may never know. ... But now we have access to the full Monty. And Lawrence Latif had a similar thought:
Intel uses the same piece of silicon [for] its Xeon E5s and Core i7-3000-series. ... Core i7s top out with six cores and 15 MB of shared L3. But the die [has] eight cores and 20 MB...cache. ... The modularity of this design is enabled by the same ring bus concept first introduced in...Sandy Bridge...more than a year ago. ... You have cores, PCI Express control, QPI links, and a quad-channel memory controller. ... Because each core is tied to a 2.5 MB slice of L3 cache, its relatively easy...to create a large number of derivative products. ... For a product like Core i7-3960X, Intel simply snipped two cores and their...cache.
Intel's Xeon E5 chips will be marketed for both near-line servers...and high-end workstations. ... However Intel's Core i7-3960X is also used as a single processor workstation chip with...the ability to use non-ECC RAM and in some cases significantly higher clock speed. And Finally...
One should not underestimate the advantage that Intel's Xeon E5 has in accessing more RAM [which] could be the biggest selling point for Xeon E5 chips in single processor workstations. ... Xeon E5...attractiveness varies with the workload. The Core i7-3960X setup will be cheaper...however if you use vast datasets then there's no question that the Xeon...was worth waiting for.
