Intel this week released Xeon E5-1600 v2 and E5-2600 v2 microprocessors for single- and dual-socket systems. New Xeon CPUs are built on more optimized and energy efficient 22nm Ivy Bridge-EP microarchitecture, and feature up to 50% more cores and up to 25% more cache at the same power envelope as previous generation of Xeon E5 products. Additionally, the processors incorporate Digital Random Number Generator, new Float 16 instructions, and have higher memory bandwidth due to added support for DDR3-1866 memory. The E5-1600v2 and E5-2600v2 CPUs are backwards compatible with existing socket 2011 motherboards.
Xeon E5-1600 v2 processors for single-socket workstations have very similar specifications to Core i7 Extreme parts, that were also launched this week. Xeon E5-1620 v2 is an entry level model. It has 4 cores operating at 3.7 GHz, and can simultaneously execute 8 threads, which is identical to the i7-4820K. Both E5-1620 v2 and i7-4820K CPUs have 3.9 GHz maximum Turbo Boost frequency, 10 MB L3 cache and 130 Watt TDP. Priced at $294, the 1620 v2 is about 10% less expensive than the i7-4820K.
Six-core E5-1650 v2 and E5-1660 v2 operate at 3.5 GHz and 3.7 GHz, that is 100 MHz faster than Core i7-4930K and i7-4960X. Remaining specifications of these Xeon E5 processors are not different from the Core i7 parts: 3.9 GHz and 4 GHz Turbo Boost speed, 12MB and 15MB L3 cache, and 130 Watt TDP. The official prices of the E5-1650 v2 and E5-1660 v2 models are $583 and $1080:
|Core i7-4820K||4 / 8||3.7 / 3.9 GHz||10 MB||DDR3-1866||130 Watt||$323|
|Xeon E5-1620 v2||4 / 8||3.7 / 3.9 GHz||10 MB||DDR3-1866||130 Watt||$294|
|Core i7-4930K||6 / 12||3.4 / 3.9 GHz||12 MB||DDR3-1866||130 Watt||$583|
|Xeon E5-1650 v2||6 / 12||3.5 / 3.9 GHz||12 MB||DDR3-1866||130 Watt||$583|
|Core i7-4960X||6 / 12||3.6 / 4 GHz||15 MB||DDR3-1866||130 Watt||$999|
|Xeon E5-1660 v2||6 / 12||3.7 / 4 GHz||15 MB||DDR3-1866||130 Watt||$1080|
Xeon E5-2600 v2 lineup consists of 18 microprocessors, including 2 entry-level models, 2 low-power models, six premium / high performance chips, and a handful of mainstream CPUs. Entry-level parts are quad-core Xeon E5-2603 v2 and E5-2609 v2, clocked at 1.8 GHz and 2.5 GHz respectively. They do not support Hyper-Threading technology, lack Turbo Boost feature, and are limited to DDR3-1333 memory. However, with official prices lower than $300 they are the least expensive products from the E5-2600 v2 series.
Two low power chips in the E5-2600 v2 series are Xeon E5-2650L v2 and E5-2630L v2. The 2650L v2 with 10 cores and Hyper-Threading feature is ideal for heavily multi-threaded applications, when low power consumption is a must. The CPU runs at 1.7 GHz, or up to 2.1 GHz, and it has 70 Watt TDP. When high per-core performance is required then the six-core E5-2630L v2 would be a better fit due to higher 2.4 GHz operating frequency. This processor has 60 Watt TDP, and it is priced at $612.
Mainstream E5-2600 v2 CPUs pack from 6 to 10 cores, and from 15 MB to 25 MB of L3 cache. They support DDR3-1600 or DDR3-1866 memory, and have TDP ranging from 80 Watt for 6-core parts, and up to 130 Watt for the E5-2690 v2. Official prices of these CPUs start at $406. The fastest from mainstream SKUs is E5-2690 v2, which sports 10 cores and 3 GHz clock speed. With a price sticker of $2057, it is also the most expensive from all mainstream Xeon E5 CPUs.
High-performance and premium E5-2600 v2 processors come with higher operating frequency or more CPU cores. The E5-2637 v2, E5-2643 v2, E5-2667 v2 and E5-2687W v2 have from 4 to 8 cores, 3.3 GHz - 3.5 GHz clock speeds, and Turbo Boost frequency reaching 4 GHz for some parts. The main advantage of premium E5-2695 v2 and E5-2697 v2 models is higher core count (12 cores), and increased size of L3 cache. The E5-2695 v2 and E5-2697 v2 run at 2.4 and 2.7 GHz, and the Turbo technology can boost frequency by another 800 MHz when needed. Premium parts come with premium prices: $2336 for the Xeon E5-2695 v2, and $2614 for the E5-2697 v2. All performance and premium SKUs have 115 Watt or higher TDP:
