Power consumption

By the virtue of the impressive 22nm Hi-K metal-gate tri-gate 22nm CMOS with 9 metal layers, Intel has been able to increase the maximum core count by 50% (15 vs 10) and the clockspeed by 17% (2.8GHz vs 2.4GHz) while the TDP has only increased by 19% (155W vs 130W). Intel claims that the actual power usage of the new flagship E7, the 155W 4890 v2, is actually lower than the previous 130W TDP Xeon E7-4870 at low and medium loads.

At maximum load, Intel claims you get about 50% higher power consumption for twice as much performance. At idle and low loads, it seems that the 155W Xeon 4890 v2 is a lot more efficient. That makes sense considering the improvements in idle/low load power use we saw with Sandy Bridge and then Ivy Bridge over the earlier Nehalem/Clarksfield offerings on desktops and laptops; it's taken some time, but the big servers are finally seeing the same improvements with Ivy Bridge EX.

    I meant, I have never seen an independent review of high-end IBM or SUN systems. We did one back in the T1 days, but the product performed only well in a very small niche.

    Contact your Oracle rep and I am sure we'd be glad to loan you a SPARC T5 server, which we have in our loaner pool for analysts and press. Would be nice if you had a more objective view on comparisons.

    If you look at Oracles Performance/Benchmark blog, we have comparisons between Xeon, Power and SPARC based on all publicly available benchmarks. As Oracle sells both x86 as well as SPARC, we sometimes have benchmarks available on both platforms to compare.

    Intel and their CPU technology continues to impress.
    Those kind of performance increase numbers must leave their competitors gasping on the mat.
    Props for the smart new chip. +1

    But can it run Crysis?

    My wife would now the answer to this considering she works for ibm but considering software costs far exceed hardware costs on a life cycle basis does anyone know what the licensing costs are between the different platforms.

    She once had me sit down to explain to her how CPU upgrades would effect db2 licenses. The system is more arcane and I'm not sure what the cost of each core is.

    For an ERP each chip type has a rated pvu metric from IBM which determines the cost of the license. Are RISC cores priced differently than x86 cores enough to partially make up the hardware costs?

    I know Oracle does that (risc core <> x86 core when it comes to licensing), but I must admit, Licensing is extremely boring for a technical motivated person :-).

    In total cost of ownership calculations, where both HW and SW as well as maintenance costs are calculated, the majority of the costs (upwards of 90%) are associated with software licensing and maintenance/administration- so although HW costs matter, it’s the performance of the HW that drives the TCO. For Oracle, both Xeon and SPARC have a per core license factor of .5x, meaning 1 x license for every two cores, while Itanium and Power have a 1x multiplier, so therefore Itanium/Power must have a 2x performance/core advantage to have equivalent SW licensing costs. IBM has a PVU scale for SW licensing, which essentially is similar to Oracle but more granular in details. Microsofts latest SQL licensing follows similarly. So clearly, performance/CPU and especially per core matters in driving down licensing costs.

    that would have be very good to test this cpu on 3D rendering benchmark.
    i can imagine the gain of time in a workstation...even the cost will be nearest a renderfarm...
    but comparing this xeon to other one in that situation should have bring a view point.

    What rendering engine are you thinking about? Most engines scale badly beyond 16-32 threads
