In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 445M v2 are massively better than the AMD Mobility Radeon HD 4270.

The GT 445M was released less than a year after the Radeon HD, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GT 445M has 512 MB more video memory than the Radeon HD, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 445M also has superior memory performance overall.

The GT 445M has 40 GB/sec greater memory bandwidth than the Radeon HD, which means that the memory performance of the GT 445M is noticeably better than the Radeon HD.

The GeForce GT 445M v2 has 144 Shader Processing Units and the Mobility Radeon HD 4270 has 40. However, the actual shader performance of the GT 445M is 164 and the actual shader performance of the Radeon HD is 24. The GT 445M having 140 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 445M delivers a significantly smoother and more efficient experience when processing graphical data than the Radeon HD.

The GeForce GT 445M v2 requires 35 Watts to run but there is no entry for the Mobility Radeon HD 4270.

GPU Mini Review

Mini ReviewOverview
GeForce GT 445M v2 is a Fast-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 GF106-N11E-GE-A1 which has 3 Stream Multiprocessors activated and thus offers 144 Shader Processing Units, 24 TMUs and 16 ROPs. The Central Unit is clocked at 570MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 625MHz.

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 35W, it is suited for 15" or larger laptops.

Performance
Gaming benchmarks put its performance almost on level with the desktop GeForce GT 450 v4.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 445M v2.
Mobility Radeon HD 4270 is an entry-class GPU part of the Mobility Radeon HD 4000 Series released from 2009 to 2010.
It uses shared memory so the performance is very very limited and not recommended for even the casual gamers since only old games (before 2005) will run smoothly at decent settings. Today's games are most likely unplayable.
