The graphics engine has been overhauled and is DirectX 11 compatible. The GPU core is armed (depending on mode) with sixteen EUs -- Execution Units (another synonym for unified processors like CUDA cores / Execution Units / Shader Cores / Stream processors). Clarkdale had eight of these, Sandy Bridge has twelve with Ivy Bridge containing four more EUs.
Each Execution Unit can manage more work per clock opposed to the older ones as well. Now there are two different GPU configurations as Intel applied a dual-graphics core to segment their products, available with 1 core (Intel HD Graphics 2500) and 2 cores (Intel HD Graphics 4000). A single GPU core holds 8 EUs and some of Ivy Bridge Core i5 and higher products will have two of these cores, so we'll see configurations with 8 (Core i3) or 16 (Core i5/i7) EUs.
So one last time, as you can understand from the specifications, don't expect heaps of gaming and fragging fun (though very simple games should be playable) but see this more as a desktop integration and implementation for very good Windows usage and, importantly, high-definition 1080P transcoding, decoding and acceleration.
The AVX (Advanced Vector Extension) Instruction Set
Certain improvements that will boost its performance in general applications by around 20% compared to Core i7 "Sandy Bridge" chips can be found in enhanced AVX acceleration. AVX stands for Advanced Vector Extensions. AVX is very well suited for floating-point-intensive applications and has become really popular.
AVX provides features and instructions. AVX is a sophisticated form of SSE. Intel opened up the data path which has been expanded from 128 bits to 256 bits, the two-operand instruction limit is increased to three operands, and advanced data re-arrangement functions are included. Now, AVX doesn't just add new instructions, Intel states it allows the CPU to execute older instructions more quickly over the AVX extensions as well.
AMD also has it planned for all their next-generation processors. So let's put it really simply; SB and IB processors will support running x87 FPU code which is capable of up to 2GB/s of double-precision throughput per core. Now here is the trick, the very same amount of work once written to be supported over the AVX extensions boils down to a 4x performance increase (theoretical) so that's 8GB/s per core (double precision), a fourfold increase in performance.
Software that caters for and supports AVX will show huge performance incensement, transcoding for example.
Core i5 3570K processor review We review the Core i5 3570K Ivy bridge processor. Will Ivy Bridge be the processor series everything you expected? Go find out in this extensive review here at Guru3D.
Core i5 2500K and Core i7 2600K review Today we test and review Sandy Bridge, the Intel Core i7-2600K and Intel Core i5-2500K processors. We will pair the 2600K processor with the Intel Desktop Motherboard DP67BG and also run a test with the Intel Core i5-2500K processor on a Intel DH67BL motherboard
Core i5 655K and Core i7 875K processor review Intel today releases two new processors targeted at a somewhat more enthusiast audience. Yes, processors for tweakers and overclockers. On socket LGA 1156 Intel now releases two K series processors. The 32nm Intel Core i5-655K processor has the very same specifications as the Core i5 650; it will operate at 3.2 GHz, will feature two cores with Hyper-Threading technology, sport 4MB of L3 cache and will be made using 32nm process technology. The difference between the 650 and 655K is the unlocked multiplier only. Then we have the enthusiast class Intel Core i7-875K processor, it has the very same specifications as the Core i7 870; it will operate at 2.93GHz, will feature four cores with Hyper-Threading technology, sport 8MB of L3 cache and will be made using 45nm process technology. The only difference between the two central processing units (CPUs) will be the unlocked multiplier on the 875K chip, which will allow overclockers and enthusiasts to easily boost clock-speed of the product without the necessity of overclocking other parts of their systems.
Core i5 650 - 660 and 661 processor review The time has come for Intel to debut a new line of mainstream 32nm processors, which we have all learned to recognize under the codename 'Clarkdale', the new CPUs will be aimed at the mainstream desktop PC segment and will complement the chip maker's Core i3 and Core i5 line of products. The Intel processor lineup will include the Core i3 530 and 540 models, as well as the Core i5 650, 660, 661, and 670, which will be featured with Hyper-Threading, 4MB of L3 cache and support for dual-channel DDR3-1333 memory. Well, that and an integrated GPU as well of course. Guru3D will put the Core i5 650, 660 and 661 to the test.
