Processors Haswell-E (22 nm) will debut in the second half of 2014. The good news for enthusiasts is that the older models Haswell-E will have 8 cores (with Core i7-4960X only six cores) and four-channel memory controller DDR4. On the CPU built into the body lines of PCI-E 3.0 (8Gb / s) chip maker is still saving: they will be 40, as in the current models of Sandy Bridge-E. Ability to work graphic ligaments AMD and Nvidia to speed 2×16, 2×16 + x8 and 3×8. All processors Intel Haswell-E will have an unlocked multiplier to increase.
Its family of Haswell-E chips will include 6 and 8 physical cores, up to 20 MB of shared cache in the third level, the controller DDR4-2133, technology support Hyper-Threading (multi-threading), and Turbo Boost 2.0 (dynamic overclocking). TDP CPU future will be 130-140 watts. Noteworthy is the fact that Intel is going to abolish native support ligaments 4-Way SLI and 4-Way CrossFireX, limited to the configuration of the three single-GPU graphics cards. However, the motherboard manufacturers will certainly be able to realize the aforesaid support ligaments through chip switches PLX PEX.
The next slide shows another interesting detail: at Haswell-E will be a maximum of 40 lines PCI Express 3.0, ie the younger 6-core models such lines may be less. The list of supported processor instruction is identical novelties family Haswell (LGA1150).
Single-chip chipset Intel X99 Express (Wellsburg-X) communicates with the CPU via DMI 2.0. Its physical dimensions are 23 x 22 mm, TDP – 6.5 watts. This chipset includes the controllers USB 2.0 (8 channels), USB 3.0 (6 channels), SATA 6 Gb / s (10 channels), 8 lines PCI-E 2.0 for the “external” controllers (network, sound), and a clock generator.
Processors for socket LGA2011-3 will be physically compatible with current motherboards LGA2011, and vice versa: CPU lines of Sandy Bridge-E and Ivy Bridge-E will not be able to work in motherboard LGA2011-3. Intel engineers have changed the designation of the contact, and to avoid damage to the processor reduced the distance between the “keys» (ILM key), so that the projections in the frame will prevent the installation of incompatible chips. The size of the PCB for the chip remains the same – 58, 5 x 51 mm, the size and shape of the contacts have not changed. Models Intel Haswell-Eis easily distinguished by the presence of precursors in a protective cover “ears.”
Traditional high heat dissipation for Intel enthusiast-level system owners will not give LGA2011-3 of a simple aluminum cooler. 130-140 watts of thermal power draw is offered with either a cooler with copper heat pipes, or by means of the liquid cooling system. Established solutions with Intel code-named T-HPHS and Channel DRX-B LC made Asetek contractors and Delta, respectively.
The general impression from Haswell-E twofold: on the one hand, Intel is going to meet the fans, increasing the number of cores, introducing DDR4 memory and extending the capabilities of the chipset. However, it is not clear why in this case to abolish native support for 4-Way SLI / CrossFireX. In Santa Clara, of course, is still time to make changes to the architecture of next-gen platform.
Processors Intel Haswell-E support memory UDIMM and RDIMM DDR4 typical server without error checking (ECC). DDR4 standard modules to operate at a voltage of 1.2 V, but it is obvious that for the first time, manufacturers of RAM for overclockers will be served at the bar DDR4 higher voltage – about 1.35 V.
