To test the HD 4000 Graphics we pitted our HD 4000 toting Intel i5-2570K up against the processor it’s replacing - the HD 3000 equipped Intel i5-2500k. This doesn’t come without its downsides though, as we’ve (and indeed most others) have found that Ivy Bridge based CPUs have a very high heat density, meaning they can often run warmer than their technically inferior predecessors. Importantly it’s also increased the number of shader cores (or as Intel calls them, execution units) from 12 to 16 - a 30% bump.Ĭlick to enlargeAside from these architectural tweaks, the GPU also obviously transitions down onto Intel’s new 22nm Tri-gate, a move which it claims allows it to deliver the same performance at up to half the power consumption. So what has Intel done to give it reason to kick up so much fuss over the HD 4000 GPU? Well, for a start it’s added DirectX 11 support, meaning that the HD 4000 is capable of taking advantage of all the lovely shiny features of the API, such as tessellation and high definition ambient occlusion. This is especially true now that AMDs FM1 APUs are in the marketplace, as their onboard graphic cores comprehensively outperformed the HD 3000 GPU that most of Intel’s Sandy Bridge CPUs sport. In truth though it’ll take more than a clever line on a presentation slide to impress us, as Intel’s onboard graphics offerings have often fell short of where we’d like them to be. It’s even labelled the switch from 32nm Sandy Bridge to 22nm Ivy Bridge as ‘more than a tick’ - a reference to Intel’s well known tick-tock strategy and an indication that the marketing chaps over in the good ole US of A are really rather pleased with what they’re bringing to market. Intel HD 4000 InvestigationIntel has been decidedly bullish about the HD 4000 GPU that’s tucked alongside the four Ivy Bridge based cores of every Intel Core i5-3570K and Core-i7 3770(K) processor.
