We can't go into detail on this other Ivy Bridge notebook just yet due to NDA reasons, but we can say that it included a 35W TDP dual-core Ivy Bridge CPU. For example, in another Ivy Bridge notebook, the HD 4000 averaged about 10 percent slower compared to the below results from the MSI barebones. For example, notebooks sporting a Core i7-3610QM will have their integrated HD 4000 GPUs operating 150MHz slower than the same GPU found in the i7-3720QM or i7-3820QM.Ī general verdict on the HD 4000 is thus a bit difficult as performance will likely vary to some extent depending on the CPU. Differing CPU models will have HD 4000 GPUs running at different maximum and minimum speeds, a common occurrence with Sandy Bridge notebooks and HD 3000 GPUs. The GPU clock will also directly impact the performance, of course. Dual-core and quad-core Ivy Bridge CPUs will have 3MB-4MB and 6MB-8MB of 元 cache, respectively, so the HD 4000 in quad-core processors should theoretically outperform its dual-core counterparts. The integrated GPU now has a larger cache as well that is shared with the CPU 元, but how much cache it has will be dependent on the Ivy Bridge CPU. System RAM running at 1333MHz is common, but our test unit will be running a bit faster with RAM clocked at 1600MHz. Since the GPU has no dedicated VRAM, it must operate in accordance with the main memory and its RAM clock. Still, the performance of the HD 4000 is dependent on several other factors. With the jump HD 4000, Intel is planning to mitigate this shortcoming to some extent by upgrading the video decoder ( MFX), increasing the number of execution units from 12 to 16 and adding support for DirectX 11 Shader Model 5.0. 3D games or programs, however, will put the integrated GPU to a grinding halt. The Sandy Bridge GPU is quick enough for most everyday tasks including Internet, HD video playback. It’s below RM 300 now and allows you better in-game display quality.Whether it's an office notebook or budget offering, the current HD 3000 graphics can be found throughout the entire spectrum. If you want to play some games, consider spending on something like say the HD 6670. It still doesn’t quite cut it for games, looks like it’s playable for certain games at low settings, for example Lost Planet 2 at lowest details. The HD 4000 shows quite some improvement over the HD 3000 series and it can now run Alien vs Predator and Lost Planet 2. 2 tests of 720p tests were done, one with the usual details as was used in other graphic card review, and the other is on lowest setting to see how the onboard GPU copes with it. Seeing it’s an onboard GPU, the tests were confined to 720p. With the Core i7-3770S at – it wouldn’t be justified to not test the graphical capability of the said processor.
