In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9800 GT are very slightly better than the AMD Radeon HD 6670.

The Radeon HD 6670 has a 200 MHz higher core clock speed than the GeForce 9800 GT, but the GeForce 9800 GT has 32 more Texture Mapping Units than the Radeon HD 6670. As a result, the GeForce 9800 GT exhibits a 14.4 GTexel/s better Texture Fill Rate than the Radeon HD 6670. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon HD 6670 has a 200 MHz higher core clock speed than the GeForce 9800 GT, but the GeForce 9800 GT has 8 more Render Output Units than the Radeon HD 6670. As a result, the GeForce 9800 GT exhibits a 3.2 GPixel/s better Pixel Fill Rate than the Radeon HD 6670. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon HD 6670 was released over a year more recently than the GeForce 9800 GT, and so the Radeon HD 6670 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 9800 GT.

The Radeon HD 6670 has 512 MB more video memory than the GeForce 9800 GT, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon HD 6670 also has superior memory performance overall.

The Radeon HD 6670 has 6.4 GB/sec greater memory bandwidth than the GeForce 9800 GT, which means that the memory performance of the Radeon HD 6670 is marginally better than the GeForce 9800 GT.

The Radeon HD 6670 has 480 Shader Processing Units and the GeForce 9800 GT has 112. However, the actual shader performance of the Radeon HD 6670 is 192 and the actual shader performance of the GeForce 9800 GT is 168. The Radeon HD 6670 having 24 better shader performance is not particularly notable, as altogether the GeForce 9800 GT performs better when taking into account other relevant data.

The Radeon HD 6670 transistor size technology is 25 nm (nanometers) smaller than the GeForce 9800 GT. This means that the Radeon HD 6670 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 9800 GT. While they exhibit similar graphical performance, the Radeon HD 6670 should consume less power than the GeForce 9800 GT.

The Radeon HD 6670 requires 66 Watts to run and the GeForce 9800 GT requires 105 Watts. We would recommend a PSU with at least 400 Watts for the Radeon HD 6670 and a PSU with at least 400 Watts for the GeForce 9800 GT. The GeForce 9800 GT requires 39 Watts more than the Radeon HD 6670 to run. The difference is significant enough that the GeForce 9800 GT may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon HD 6670.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6670 is a fast-middle-class Graphics Card based on the second revision of the Terascale Architecture.

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.

GPU
It equips a GPU codenamed Turks XT which has 8 Compute Units activated and thus offers 480 Shader Processing Units, 24 TMUs and 8 ROPs.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The memory clock operates at 1000MHz. The size of the frame buffer is adequate.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.

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

Power Consumption
With a rated board TDP of 66W, 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 somewhere between GeForce GT 440 and GeForce GTS 450.

System Suggestions
We recommend a modest processor (Intel Core i3/AMD Phenom) and 4GB of RAM for a system with Radeon HD 6670.
Overview
GeForce 9800 GT is a High-End Graphics Card based on the first revision of the Tesla Architecture.

Architecture
Tesla was NVIDIA's First Unified Shader Architecture.

GPU
It equips a GPU Codenamed G92-270-A2 which has 7 Stream Multiprocessors activated and thus offers 112 Shader Processing Units, 56 TMUs and 16 ROPs. The Central Unit is clocked at 600MHz.

Memory
The GPU accesses a 512MB frame buffer of GDDR3, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

Features
DirectX 10.0 Support (10.0 Hardware Default) and support for SLI, NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

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

Power Consumption
With a rated board TDP of 105W, it requires at least a 400W PSU and it requires at least one 6-pin available connectors.

Performance
GeForce 9800 GT is a direct re-brand of GeForce 8800 GT.
Gaming benchmarks put its performance somewhat below a Radeon HD 4770, meaning it is much faster than Radeon HD 3870.
