Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8670 (OEM) are massively better than the Nvidia GeForce GT 720.
The HD 8670 has a 203 MHz higher core clock speed and 8 more Texture Mapping Units than the GeForce GT 720. This results in the HD 8670 providing 11.2 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 8670 has a 203 MHz higher core clock speed than the GeForce GT 720 and the same number of Render Output Units. This results in the HD 8670 providing 1.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GeForce GT 720 was released less than a year after the HD 8670, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The HD 8670 has 1024 MB more video memory than the GeForce GT 720, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 8670 also has superior memory performance overall.
The HD 8670 has 59.2 GB/sec greater memory bandwidth than the GeForce GT 720, which means that the memory performance of the HD 8670 is much better than the GeForce GT 720.
The Radeon HD 8670 (OEM) has 384 Shader Processing Units and the GeForce GT 720 has 192. However, the actual shader performance of the HD 8670 is 343 and the actual shader performance of the GeForce GT 720 is 153. The HD 8670 having 190 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 8670 delivers a significantly smoother and more efficient experience when processing graphical data than the GeForce GT 720.
The Radeon HD 8670 (OEM) requires 75 Watts to run and the GeForce GT 720 requires 19 Watts. We would recommend a PSU with at least 400 Watts for the HD 8670 and a PSU with at least 300 Watts for the GeForce GT 720. The HD 8670 requires 56 Watts more than the GeForce GT 720 to run. The difference is significant enough that the HD 8670 may have an adverse affect on your yearly electricity bills in comparison to the GeForce GT 720.
|Mini Review||Overview |
Radeon HD 8670 (OEM) is an OEM Only, Fast-Middle-Class Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.
The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support.
It equips a GPU Codenamed Oland XT which has 6 Compute Units activated and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit is clocked at 1000MHz and goes up to 1050MHz, in Turbo Mode.
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 1150MHz.
With a rated board TDP of 60W, it requires at least a 400W PSU and relies entirely on the PCI Slot for power, meaning no extra connectors are required.
Radeon HD 8670 (OEM) Competes with GeForce GTX 750 but the latter is much faster and slightly more efficient.
It proves to be as fast as Radeon HD 7750.
Radeon HD 8670 (OEM) is best suited for resolutions up to and including 1600x900. We recommend a Decent Processor (Intel Core i3 Dual Core/AMD FX Quad Core) and 8GB of RAM for Optimal Performance.
GeForce GT 720 is a Middle-Class Graphics Card based on the Second Revision of the Kepler Architecture.
This Graphics Card Equips the Kepler GK208 GPU which is essentially a power optimized version of the GK107 GPU. Whereas it still has a count of 2 Stream Multiprocessors, the bus-width has been cut in half to allow for even a smaller power consumption and consequently a cooler operating temperature.
Additionally, the GK208 GPU allows the Central Unit to reach a significant higher frequency, thanks to the Kepler Boost 2.0 Technology. The better the laptop's cooling system, the higher the frequency.
It equips a GPU Codenamed GK208 which has 1 Stream Multiprocessor activated and thus offers 192 Shader Processing Units, 16 TMUs and 16 ROPs. The Central Unit is clocked at 797MHz.
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.
DirectX 12.0 Support (11.0 Hardware Default) and support for Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 19W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.
Gaming benchmarks put its performance on average with the older GeForce GT 530.
We recommend a Modest Processor (Pentium G) and 8GB of RAM for a system with GeForce GT 720.
