|Mini Review||Overview |
GeForce GTX 675MX is a High-End 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 Kepler GK104-N13E-GSR-A2 which has 5 Stream Multiprocessors activated and thus offers 960 Shader Processing Units, 80 TMUs and 32 ROPs. The Central Unit is clocked at 600MHz.
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 256-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 SLI, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 100W, it is suited for very large sized laptops.
Gaming benchmarks indicate is not too far from the desktop GeForce GTX 650 Ti Boost Edition.
We recommend a Power Processor (Intel Core i7 Mobile) and 8GB of RAM for a system with GeForce GTX 675MX.
Radeon HD 7570M is an Entry-Level Mobile Graphics Card based on the second revision of the Terascale Architecture.
The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.
It equips a GPU codenamed Thames PRO which has 6 Compute Units activated and thus offers 480 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit runs at 500MHz.
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 64-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 800MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.
With a rated board TDP of 13W, it is suited for average sized laptops.
Gaming benchmarks put its performance somewhere on average with GeForce GT 525M.
We recommend a Modest Processor (Intel Core i3 Mobile and 4GB of RAM for a system with Radeon HD 7570M.
