The Intel 4th generation Core i7-4790 processor is based on the new 22nm Haswell Microarchitecture for improved CPU performance. Advanced power management innovations help keep power consumption in check. New compute instructions ensure enhanced performance per cycle. Improved Intel integrated graphics enables discrete-level graphics performance. Extract more power from your Haswell core-based processor.
Haswell Microarchitecture on 22nm process
The new Microarchitecture (code name Haswell) has full integrated voltage regulator (FIVR) for simplified motherboard design. It delivers improved CPU performance and enhanced overclocking over its previous generation Microarchitecture.
New 4 generation Intel Core processor family instructions
Haswell core-based processors come with Intel Advanced Vector Extensions 2 (Intel AVX2). Intel AVX2 expands integer data to 256-bit SIMD to increase the performance of integer operations. It also offers new capabilities such as Gather and FMA (Fused Multiply-Add). Additional new instructions accelerate key algorithms including parallel extract/deposit, bit manipulation operations and new rotates/multiplies/shift. The AES-NI performance is also improved.
Intel processor graphics with Dx11.1 & OPenCL 1.2
Haswell core-based processors offer improved integrated graphics. The integrated graphics supports DirectX 11.1 for optimized graphics performance and OpenGL 3.2 & OpenCL 1.2 for enhanced general purpose computing in GPGPU supported applications. It also features digital display repartition, where digital display ports are wired directly to the CPU and analog displays are handled by a Random Access Memory Digital-to-Analog Converter (RAMDAC) located in the Platform Controller Hub (PCH). It supports up to three independent displays: HDMI, DVI, Display Port, VGA (via Lynx Point).
Haswell power management innovation
Haswell core-based processors offer advanced power management. It has 20x + improvement from prior generation and is automatic, continuous, fine-grained, transparent to well written SW.
Intel Turbo Boost Technology 2.0
More intelligent, energy-efficient, and dynamic than previous generation, Intel Turbo Boost Technology 2.0 gives you accelerating performance when you need it. It delivers an even greater automatic speed increase by allowing processor cores to run faster than the base operating frequency for demanding applications if the processor is operating below power, current, and temperature specification limits.
