Intel this week launched the second generation of Xeon E7 microprocessors for mission critical applications and big data computing. Branded as Xeon E7-2800 v2, E7-4800 v2 and E7-8800 v2, the CPUs provide up to 50% more cores, up to 25% more cache, up to 4x times of I/O bandwidth, and up to 3x times of supported RAM than the first generation of Xeon E7 products. These improvements, combined with microarchitecture enhancements, allow Xeon E7 v2s to perform up to 2 times faster than their predecessors. The new CPUs also incorporate a number of reliability, availability and serviceability features, such as Run Sure Technology, enhanced Machine Check Architecture, MCA Recovery Execution Path, and PCIe Live Error Recovery. The Xeons are aimed for 2-, 4- and 8-socket servers, but may support up to 32 sockets when used with third party node controllers. More than 20 OEM manufacturers already announced and are going to announce systems, designed around new processors.
The E7 v2 family consists of E7-2800 v2, E7-4800 v2 and E7-8800 v2 CPUs for two-, four- and eight-socket servers respectively.
The E7-2800 v2 series is comprised of 12-core E7-2850 v2 SKU, along with 15-core E7-2870 v2, E7-2880 v2 and E7-2890 v2. The processors have from 24 MB to 37.5 MB of L3 cache, and operate at 2.3 GHz - 2.8 GHz frequency depending on SKU. The Thermal Design Power of the CPUs ranges from 105 Watt for the E7-2850 v2 model, and up to 155 Watt for the E7-2890 v2. These Xeons are priced from $2558 to $6451.
Similar models with exactly the same specifications exists in both the E7-4800 v2 and E7-8800 v2 series. Xeon E7-4850 v2, E7-4870 v2, E7-4880 v2 and E7-4890 v2 SKUs are slightly more expensive, and their prices range from $2837 to $6619. Official prices of the E7-8850 v2, E7-8870 v2, E7-8880 v2 and E7-8890 v2 start at $3059, and go all the way up to $6841.
In addition to the aforementioned mainstream products, the E7-4800 v2 series includes Xeon E7-4809 v2 6-core processor, 8-core Xeon E7-4820 v2, 10-core Xeon E7-4830 v2, and 12-core Xeon E7-4860 v2. The CPUs have from 12 MB to 30 MB of last level cache, 105 Watt or 130 Watt TDP, and they are priced from $1223 to $3838.
Furthermore, the E7 v2 family comes with three frequency optimized models, E7-8857 v2, E7-8891 v2 and E7-8893 v2. The E7-8857 v2 has 12 CPU cores, and it is the only E7 v2 processor that does not support Hyper-Threading. This part has 3 GHz clock speed, 130 Watt TDP, and it costs $3838. The E7-8891 v2 and E7-8893 v2 have 10 and 6 cores respectively, and run at 3.2 GHz and 3.4 GHz, with the maximum Turbo Boost frequency of 3.7 GHz. Both chips have 37.5 MB cache, 155 Watt TDP, and their official price $is 6841.
Xeon E7-8800 v2 series also includes Xeon E7-8880L v2 low power processor. This chip fits into 105 Watt thermal envelope, which is remarkable considering that it has 15 cores, 37.5 MB cache, and runs at 2.2 GHz.
All Xeon E7 v2 CPUs utilize socket LGA2011-1. Specifications of new microprocessors are provided below:
