![]() AMD A6-3420M (1.5-2.4 GHz), 6 GByte DDR3-RAM (1333 MHz), AMD Radeon HD 700 / 900 MHz (GPU-Treiber: 8.9) ⇒ A typical entry-level card often used in inexpensive multimedia notebooks.Intel Core i7-2670QM (2.2-3.1 GHz), 8 GByte DDR3-RAM (1333 MHz), Nvidia GeForce GT 672 / 800 MHz (GPU-Treiber: 285.64) ⇒ Currently Nvidia's most successful mid-range GPU.Intel Core i7-2630QM (2.0-2.9 GHz), 8 GByte DDR3-RAM (1333 MHz), Intel HD Graphics 650-1100 MHz (GPU-Treiber: 8.) ⇒ A notebook with the typical Sandy Bridge HD 3000 GPU.To give an impression of what the HD 4000 will be up against, we list other low-end and mid-range graphics cards that are currently available: 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. Whether it's an office notebook or budget offering, the current HD 3000 graphics can be found throughout the entire spectrum. ![]()
