|Mini Review||Overview |
GeForce GT 720M is a entry-level Mobile Graphics Card based on the second revision of the Fermi 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.
It equips a GPU Codenamed GF117-N14M-GE which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit is initially clocked at 625MHz and may reach up to 938MHz, in Turbo Mode.
Additionally, GF117 is built using a 28nm technology.
The GPU accesses a 1GB frame buffer of DDR3, through a 64-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 Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 33W, it is suited for average sized laptops.
GeForce GT 720M is essentially a fast GeForce GT 620M with the option for the Boost Clock which depends on the laptop's cooler.
Gaming benchmarks indicate its performance is slightly below the older GeForce GT 635M.
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 720M.
Radeon HD 7750M is a Fast-Middle-Class Mobile Graphics Card based on the First revision of the GCN Architecture.
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.
It equips a GPU codenamed Chelsea LE which has 8 Compute Units activated and thus offers 512 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit Initially Operates at 575MHz and goes up to 675MHz, in Turbo Mode.
The GPU accesses a 1GB frame buffer of fast DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 900MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.
With a rated board TDP of 32W, it is suited for 15" or larger laptops.
Gaming benchmarks put its on average with NVIDIA's GeForce GT 640M.
We recommend a Modest Processor (Intel Core i3 Mobile) and 4GB of RAM for a system with Radeon HD 7730M.
