In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 4600 Desktop are noticeably better than the Intel HD Graphics 4000 Desktop.

The Graphics 4000 has a 250 MHz higher core clock speed and the same number of Texture Mapping Units as the Graphics 4600. This results in the Graphics 4000 providing 1 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Graphics 4000 has a 250 MHz higher core clock speed and 2 more Render Output Units than the Graphics 4600. This results in the Graphics 4000 providing 1.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Graphics 4600 was released over a year more recently than the Graphics 4000, and so the Graphics 4600 is likely to have better driver support, meaning it will be more optimized for running the latest games.

The HD Graphics 4600 Desktop and the HD Graphics 4000 Desktop have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the HD Graphics 4600 Desktop and the HD Graphics 4000 Desktop are the same, which means the Graphics 4600 and the Graphics 4000 have equal limitations when it comes to graphical data transfer.

The HD Graphics 4600 Desktop has 80 Shader Processing Units and the HD Graphics 4000 Desktop has 16. However, the actual shader performance of the Graphics 4600 is 157 and the actual shader performance of the Graphics 4000 is 74. The Graphics 4600 having 83 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics 4600 delivers a marginally smoother and more efficient experience when processing graphical data than the Graphics 4000.

The HD Graphics 4000 Desktop requires 77 Watts to run but there is no entry for the Graphics 4600. We would recommend a PSU with at least 300 Watts for the Graphics 4000, but we do not have a recommended PSU wattage for the Graphics 4600.

GPU Mini Review

Mini ReviewIntel HD Graphics 4600 Desktop is the successor to Intel HD 4000 Desktop that's featured in the Haswell based desktop CPUs.
It features 20 Execution Units (80 Shader Processing Units) and its central-unit speed will range between 400MHz and 1250MHz (Turbo Boost) and that the fastest memory supported is DDR3-1600 meaning its memory-clock will operate at 800MHz, at the most.
Benchmarks indicate its performance is up to 25% better than previous Intel HD 4000. However, only Iris Graphics offer performance good enough to play all modern demanding games, some even with extremely fluent frame rates.
Intel HD Graphics 4000 Desktop are Integrated Graphics in some of Intel's Desktop Ivy Bridge Processors.

The Ivy Bridge GT2 Core includes support for DirectX 11, OpenCL 1.2 and OpenGL 4.0. Additionally, it also offers Hardware Tessellation, Dedicated L3 Cache and better Video Decoding Performance, when compared to its Predecessor.

It equips a GPU Codenamed GT2 which offers 16 Shader Processing Units, 4 TMUs and 4 ROPs. The Central Unit Initially Runs at 200MHz and goes up to 1150MHz, in Turbo Mode.

The GPU Shares the System's RAM which varies from laptop to laptop. Typically, the GPU reserves 1GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on the at which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 800MHz.
It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.

The Most Powerful Variant Offers Performance similar to a dedicated GeForce GT 620.
