Intel Core i7-5960X Haswell-E 8-Core 3.0 GHz LGA 2011-v3 140W BX80648I75960X Desktop Processor
Intel Hyper-Threading Technology (Intel HT Technology) 1 uses processor resources more efficiently, enabling multiple threads to run on each core. As a performance feature, Intel HT Technology also increases processor throughput, improving overall performance on threaded software. With Intel HT Technology, multimedia enthusiasts can create, edit and encode graphically intensive files while running background applications, such as virus protection software, without compromising system performance. Intel Turbo Boost Technology 2.01 automatically allows processor cores to run faster than the rated operating frequency if they’re operating below power, current and temperature specification limits. Intel Turbo Boost Technology 2.0 is activated when the Operating System (OS) requests a frequency higher than the rated frequency of the processor. Whether the processor enters into and the amount of time the processor spends in the Intel Turbo Boost Technology 2.0 state depends on the workload and operating environment. Maximum turbo frequency indicates the highest possible frequency achievable when conditions allow the processor to enter turbo mode. Intel Turbo Boost Technology frequency varies depending on workload, hardware, software and overall system configuration.
Last year, Intel released its new high-end desktop platform, the X99, which uses the new LGA2011-v3 socket. The CPUs launched for this platform are codenamed “Haswell-E,” and the most high-end CPU lauched for this platform is the Core i7-5960X, which has eight cores (16 threads thanks to the Hyper-Threading technology), 3.0 GHz clock (3.5 GHz maximum clock, through Turbo Boost technology), and the support for quad-channel DDR4 memories. Let’s benchmark this beast and see how well it performs.
The new X99 platform comes to replace the X79 platform, and the main difference between the two is the support to DDR4 memory instead of DDR3. (Both support quad-channel memory access.) This platform uses the new LGA2011-v3 socket, which is not compatible with LGA2011 CPUs from the X79 platform. LGA2011-v3 CPUs can have 40 or 28 PCI Express 3.0 lanes, and the exact way they are connected to the PCI Express slot and devices will depend on the motherboard. Since it is targeted to the high-end user, processors from the X99 platform don’t come with an embedded graphics adapter.The Core i7-5960X is the most high-end CPU from this family and, so far, the most high-end desktop processor available on the market. It has 40 PCI Express 3.0 lanes, base clock of 3.0 GHz with turbo clock up to 3.5 GHz, 140 W TDP, and supports DDR4 memory modules up to 2,133 MHz, in quad-channel configuration. It supports SSE 4.2, AVX 2.0, and AES instruction sets. The Core i7-5960X has eight processing cores, but thanks to the Hyper-Threading technology, it is seen as a 16-core processor by the operating system.
