Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 740M are massively better than the Intel HD Graphics 4000 Mobile.
The GeForce GT 740M has a 160 MHz higher core clock speed and 28 more Texture Mapping Units than the Graphics 4000. This results in the GeForce GT 740M providing 23.3 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 GeForce GT 740M has a 160 MHz higher core clock speed and 12 more Render Output Units than the Graphics 4000. This results in the GeForce GT 740M providing 10.4 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 GeForce GT 740M was released over a year more recently than the Graphics 4000, and so the GeForce GT 740M is likely to have better driver support, meaning it will be more optimized for running the latest games.
The GeForce GT 740M has 2048 MB video memory, but the Graphics 4000 does not have an entry, so the two GPUs cannot be reliably compared in this area.
The GeForce GT 740M has 384 Shader Processing Units and the HD Graphics 4000 Mobile has 16. However, the actual shader performance of the GeForce GT 740M is 311 and the actual shader performance of the Graphics 4000 is 86. The GeForce GT 740M having 225 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 740M delivers a noticeably smoother and more efficient experience when processing graphical data than the Graphics 4000.
The Graphics 4000 transistor size technology is 6 nm (nanometers) smaller than the GeForce GT 740M. This means that the Graphics 4000 is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GT 740M.
The GeForce GT 740M requires 45 Watts to run and the HD Graphics 4000 Mobile requires 55 Watts. The Graphics 4000 requires 10 Watts more than the GeForce GT 740M to run. The difference is not significant enough for the Graphics 4000 to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 740M.
|Mini Review||Overview |
GeForce GT 740M is a Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.
It equips a GPU Codenamed GK107-GT-740M which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 810MHz.
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and no way benefits the GPU. The Memory Clock Operates at 900MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Kepler Boost, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 45W, it is suited for average sized laptops.
GeForce GT 740M is essentially a fast GeForce GT 640M.
Gaming benchmarks indicate its Performance is around 3% worse than the older GeForce GT 650M.
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GT 740M.
Intel HD Graphics 4000 Mobile are Integrated Graphics in some of Intel's Mobile 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 650MHz and goes up to 1350MHz, in Turbo Mode.
The GPU Shares the System's RAM which varies from System to System. Typically, the GPU reserves 1.7GB. 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 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 425M.
