In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 420M are very slightly better than the Intel HD Graphics Mobile (Broadwell).

The GeForce GT 420M has a 200 MHz higher core clock speed and 12 more Texture Mapping Units than the Graphics Mobile. This results in the GeForce GT 420M providing 6.8 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 420M has a 200 MHz higher core clock speed and 2 more Render Output Units than the Graphics Mobile. This results in the GeForce GT 420M providing 1.4 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 Graphics Mobile was released over three years more recently than the GeForce GT 420M, and so the Graphics Mobile is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce GT 420M when running the latest games.

The GeForce GT 420M has 512 MB video memory, but the Graphics Mobile does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics Mobile (Broadwell) has 12 Shader Processing Units and the GeForce GT 420M has 96. However, the actual shader performance of the Graphics Mobile is 10. The GeForce GT 420M having 86 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 420M delivers a marginally smoother and more efficient experience when processing graphical data than the Graphics Mobile.

The Graphics Mobile transistor size technology is 18 nm (nanometers) smaller than the GeForce GT 420M. This means that the Graphics Mobile is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 420M. While they exhibit similar graphical performance, the Graphics Mobile should consume less power than the GeForce GT 420M.

The HD Graphics Mobile (Broadwell) requires 4 Watts to run and the GeForce GT 420M requires 23 Watts. The GeForce GT 420M requires 19 Watts more than the Graphics Mobile to run. The difference is not significant enough for the GeForce GT 420M to have a noticeably larger impact on your yearly electricity bills than the Graphics Mobile.

GPU Mini Review

Mini ReviewIntel HD Graphics Mobile (Broadwell) are integrated graphics in the budget Celeron and Pentium Broadwell Mobile processors.
Their performance depends on the processor they are integrated on, as the latter defines the Base and Boost Clock, as well as on the SYSTEM RAM, which defines the operating memory clock, and whether the GPU accesses a 64-bit or 128-bit memory interface.
Best case scenario, the Intel HD Graphics Mobile (Broadwell) performs on par with Intel HD 4000 Graphics and so most modern demanding games will not be playable. Less graphically intense games will be playable at lower graphics settings.
Overview
GeForce GT 420M is a middle-class Mobile Graphics Card based on the first revision of the Fermi Architecture.

Architecture
The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU Codenamed N11P-GE-A1 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 4 ROPs. The Central Unit is clocked at 500MHz.

Memory
The GPU accesses a 512MB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 800MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 23W, it is suited for 15" or larger laptops.

Performance
Gaming benchmarks put its performance somewhat below a desktop GeForce GT 430.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 420M.
