In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 545 1.5GB are noticeably better than the AMD Radeon HD 6670 v2 MSI 2GB Edition.

The HD 6670 has a 80 MHz higher core clock speed and the same number of Texture Mapping Units as the GT 545. This results in the HD 6670 providing 1.9 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 HD 6670 has a 80 MHz higher core clock speed than the GT 545, but the GT 545 has 8 more Render Output Units than the HD 6670. As a result, the GT 545 exhibits a 5.1 GPixel/s better Pixel Fill Rate than the HD 6670. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 545 was released less than a year after the HD 6670, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 6670 has 512 MB more video memory than the GT 545, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GT 545 has superior memory performance.

The GT 545 has 17.1 GB/sec greater memory bandwidth than the HD 6670, which means that the memory performance of the GT 545 is slightly better than the HD 6670.

The Radeon HD 6670 v2 MSI 2GB Edition has 480 Shader Processing Units and the GeForce GT 545 1.5GB has 144. However, the actual shader performance of the HD 6670 is 192 and the actual shader performance of the GT 545 is 207. The GT 545 having 15 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 545 delivers a slightly smoother and more efficient experience when processing graphical data than the HD 6670.

The Radeon HD 6670 v2 MSI 2GB Edition requires 66 Watts to run and the GeForce GT 545 1.5GB requires 70 Watts. We would recommend a PSU with at least 400 Watts for the HD 6670 and a PSU with at least 400 Watts for the GT 545. The GT 545 requires 4 Watts more than the HD 6670 to run. The difference is not significant enough for the GT 545 to have a noticeably larger impact on your yearly electricity bills than the HD 6670.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6670 v2 MSI 2GB Edition is a special edition of AMD's fast-middle-class Radeon HD 6670 v2, created by MSI.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock runs at 667MHz and the Frame Buffer was raised to 2GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System remains the same.

Performance
Without Overclocking Out of The Box, Radeon HD 6670 v2 MSI 2GB Edition is as fast as the reference Radeon HD 6670 v2.
Overview
GeForce GT 545 1.5GB is a Fast-Middle-Class Graphics Card based on the second 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 GF116-400-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 720MHz.

Memory
The GPU accesses a 1.5GB frame buffer of DDR3, through a 192-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 SLI, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 70W, it requires at least a 400W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance slightly above Radeon HD 6670 v2.

System Suggestions
We recommend a modest processor (Intel Core i3) and 8GB of RAM for a system with GeForce GT 545 1.5GB.
