Intel Ivy Bridge benched early, shows huge leap in graphics

Intel Ivy Bridge gets pre-release test

An unofficial, pre-release benchmarking of Intel's upcoming Ivy Bridge architecture has shown an overall speed up, but most of all in graphics. Testing at AnandTech of a 3.5GHz, quad Core i7-3770K desktop chip has shown that the Intel HD 4000 integrated video is about 20 to 40 percent faster than the 3000 video on a roughly comparable earlier Core i7 using the current Sandy Bridge architecture. While still trailing behind AMD's Fusion in an A8 chip, it's enough to make games playable that wouldn't have been practical otherwise, such as running Skyrim smoothly at 1680x1050 and medium detail.

The underlying processor itself has a clear edge over Sandy Bridge. While it's at a disadvantage with four cores to the very highest-end, six-core Sandy Bridge-E processors, Ivy Bridge is about five to 20 percent faster than any of its quad-core antecedents in general use.

Graphics boosts mostly come from the higher number of execution units, at 16 versus 12, as well as DirectX 11 (OpenGL 4) effects support. Ivy Bridge as a whole gets an inherent benefit from a denser, more efficient 22-nanometer manufacturing process as well as twice the throughput for floating-point and integer divisions. It can dynamically share code elements between program threads and supports up to 2.8GHz DDR3 memory along with low-power DDR3 on slim desktops and notebooks.

Intel is now increasingly seen as shipping the first batch of Ivy Bridge Core i5 and i7 processors in late April, mixing both desktop and notebook versions. Much of the PC industry is waiting on the later than usual release and could start shipping soon afterwards.

The lineup may have the most significance for Apple, which is holding off on multiple Mac updates. Ivy Bridge should allow for OpenCL support on the integrated graphics and could deliver a larger performance boost than on Windows as a result.
