4th Gen Intel Hard disk drive Graphics

Intel debuted on-die HD graphics with the Westmere compages, although to exist precise it wasn't actually on-die only on-bundle, meaning the graphics engine was separate from the CPU. Furthermore, information technology was congenital using the 45nm process and non the aforementioned 32nm process used by the actual CPU.

Then the 2nd generation graphics (Sandy Bridge) changed all that by including the GPU on-die. Fifty-fifty though both processing units were nether the same roof, the GPU was however independent of the CPU. It featured its own clock domain that could be gear up independently and could exist powered down as needed.

This same design principle was used for Ivy Bridge, Intel merely added more horsepower. At that place were two versions of the Intel HD graphics with the Ivy Span processors using either the Hd 2500 or the faster HD 4000 engine.

The shaders, cores and execution units are what Intel calls EUs (Execution Units) with Hd 2500 featuring 6 and the speedier Hd 4000 getting sixteen. Interestingly, almost Core i5 desktop processors used the slower HD Graphics 2500 engine, while all mobile processors received the 4000 engine.

Haswell offers many more flavors of built-in graphics.

Starting at the bottom of the food concatenation we have the Intel Hard disk drive Graphics 4600/4400 and 4200. The side by side level up is the Intel Hard disk drive Graphics 5000 and then Intel Iris Graphics 5100 and Iris Pro 5200.

Now because nosotros only have the Cadre i7-4770K today we tin show you lot how the Intel Hard disk Graphics 4600 performs. This is the selection of born graphics that a wide majority of Cadre i7 (all except one) and all Core i5 desktop processors will receive. The HD 4600 gets 20 EUs, a 25% increment over Ivy Bridge. The clock speed has as well been increased from 1150MHz to 1250MHz, a balmy ix% bump in frequency.

The Intel HD Graphics 5000 and Iris Graphics 5100 receive forty EUs application them twice the ability-performance of HD 4xxx. Then the Iris Pro Graphics 5200 which still features the same 40 EUs gets a big embedded DRAM enshroud to amend bandwidth operation.
