Intel Unleashes Haswell-EX Xeon E7 V3 Processors – Up to 18 Cores, 45 MB L3 Cache, 12 TB DDR4 Memory Support and 5.7 Billion Transistors

Hassan Mujtaba

Intel has officially launched their Haswell-EX Xeon E7 V3 processor lineup aimed at the enterprise and server market. The launch lineup includes 12 new processors, all of which are derived from a single 18 core flagship Xeon part which is a beast in terms of specifications that include 18 cores, 45 MB of L3 cache, a die size of 662 mm2 and a total of 5.6 billion transistors.

Intel's Haswell-EX Xeon E7 V3 Processors Launched - Xeon E7-8890 V3 With 18 Cores Leads The Pack

The latest Haswell-EX Xeon E7 V3 lineup is based on the same Haswell architecture which was released in 2013, however, Intel has spent some time updating the performance and enhancing task specific loads which leads to better gains in server based scenarios on their existing architecture. Being 22nm, the Haswell-EX processors are massive in die size but they incorporate beefy performance due to higher number of cores, threads and overall cache available on the chips. Other similarities between the platform is that the Haswell-EX and Haswell-EP are same when looked upon from specifications but one is aimed at 2S solutions (Haswell-EP Xeon E5 V3) while the Haswell-EX is based on 4S and 8S solutions which leads to bigger server and enterprise setups. On the chipset and platform support side, Intel keeps the Haswell-EX processors compatible to their Patsburg C600 series chip sets which means they will be supported by existing platforms on LGA 2011 socket (Socket R1). This brickland platform has been running Intel's past two generation of Xeon processors including Sandy Bridge-EX, Ivy Bridge-EX and will run up to Broadwell-EX generation of Xeon processors.

Some features of the processors include up to 18 cores and 36 threads. The same flagship design ends up being scaled down to more cost effective models. These chips feature up to 45 MB of L3 cache (2.5 MB / Slice) since it is a multi-chip module and carries the integrated voltage regulator (IVR) to allow voltage and power regulation to save power consumption. There are a total of 12 processors which include the Xeon E7-8890 V3,  Xeon E7-8800 V3,  Xeon E7-8870 V3,  Xeon E7-8860 V3 which are positioned as advanced offerings that can allow up to 8S designs, have 9.6 GT/s interconnects, feature hyper threading/ turbo boost support and come with DDR4 and DDR3 memory support (1867 MHz / 1600 MHz). The standard offerings include the  Xeon E7-4850 V3 and  Xeon E7-48300 V3 which allow 4S designs while basic level  Xeon E7-4820 V3 and  Xeon E7-4809 V3 processors allow 4S scalable designs with skimmed down specs and a cut down interconnect path. Last but not least, there are four segment optimized offerings which include  Xeon E7-8891 V3 and  Xeon E7-8893 V3 for enterprise and database markets,  Xeon E7-8880L V3 for low power market and  Xeon E7-8867 V3 for HPC market.

Summing up the specifications for the flagship Xeon E7-8890 V3 processor, we are looking at 18 cores, 36 threads and 45 MB of L3 cache (LLC). Clock speeds range from 2.5 GHz base and 3.3 GHz boost while in AVX workloads, the clock speeds are throttled down to 2.1 GHz base and 3.3 GHz boost. The processor features a massive 165W TDP on a 22nm process which is due to the large die size that is 662mm2 in size and holds up to 5.6 Billion transistors. The chip is priced at $7175 US.

A complete platform can allow up to 24 DIMMs per socket (3DPC/ 96 DIMMs) with DDR3/DDR4 memory support. A full 8S server rack will be able to allow up to 12 TB of DDR4 memory support which is just insane and something completely magical for mainstream consumers. RSA capabilities include Enhanced MCA Gen2, rank sparing, address based memory mirroring, DDR4 recovery for command/address parity errors. There are also power states to allow efficient control over power resources. Following are some basic features as mentioned by Intel themselves:
