Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8670 (OEM) are significantly better than the Nvidia GeForce GT 720.

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 249.6. The HD 8670 having 57.6 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 8670 delivers a noticeably 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 300 Watts for the GeForce GT 720, but we do not have a recommended PSU wattage for the HD 8670. 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.

GPU Mini Review

Mini ReviewRadeon HD 8670 (OEM) is an OEM only, middle-class GPU based on the GCN architecture and successor to middle-class Radeon HD 6670 (later renamed as 7670).
It offers 384 Shader Processing Units on a 128-bit interface of fast GDDR5. The central unit is clocked at 1000MHz. It offers 8 ROPs and 24 TMUs. It should draw up to 75 Watts.
There are no benchmarks available and so its rank is subject to change.
This Graphics Card has 2 variants: one paired with DDR3 and another with GDDR5. This is the DDR3 version.

GeForce GT 720 is a middle-class level Graphics Card still based on the 28nm, Kepler architecture.

GeForce GT 720 offers the energy optimized GK208 Core with a SMX count of 1 and thus comes with 192 Shader Processing Units, 16 TMUs and only 8 ROPs, this on a 64-bit memory of 1GB of standard DDR3. While the central unit runs at 797MHz, the memory clock operates at 900MHz. The rated board TDP is of 19 Watts.

GeForce GT 720's performance is therefore reduced and only on pair with today's most powerful integrated graphics.
This Graphics Card needs to be paired with a decent modern processor and should only be used on a gaming mode below 720p, for optimal performance.
