In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8570D are significantly better than the AMD Radeon HD 6450.
The Radeon HD 8570D has a 219 MHz higher core clock speed and 8 more Texture Mapping Units than the Radeon HD 6450. This results in the Radeon HD 8570D providing 8.5 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 Radeon HD 8570D has a 219 MHz higher core clock speed and 4 more Render Output Units than the Radeon HD 6450. This results in the Radeon HD 8570D providing 4.3 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 Radeon HD 8570D was released over a year more recently than the Radeon HD 6450, and so the Radeon HD 8570D is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 6450.
The Radeon HD 6450 has 512 MB video memory, but the Radeon HD 8570D does not have an entry, so the two GPUs cannot be reliably compared in this area.
The Radeon HD 8570D has 256 Shader Processing Units and the Radeon HD 6450 has 160. However, the actual shader performance of the Radeon HD 8570D is 140 and the actual shader performance of the Radeon HD 6450 is 50. The Radeon HD 8570D having 90 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 8570D delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon HD 6450.
The Radeon HD 8570D transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 6450. This means that the Radeon HD 8570D is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6450.
The Radeon HD 8570D requires 65 Watts to run and the Radeon HD 6450 requires 18 Watts. We would recommend a PSU with at least 300 Watts for the Radeon HD 6450, but we do not have a recommended PSU wattage for the Radeon HD 8570D. The Radeon HD 8570D requires 47 Watts more than the Radeon HD 6450 to run. The difference is significant enough that the Radeon HD 8570D may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon HD 6450.

|Mini Review||Radeon HD 8570D is an embedded Graphics Card on the mainstream Richland APUs A8-6600 and A8-6600K. |
They offer 256 Shader Processing Units, 16 TMUs and 8 ROPs. The memory interface depends on whether or not the system's RAM is dual channelled.
While the central unit runs at 844MHz (for 6600K, 800MHz for 6600), since the GFX doesn't have dedicated memory, the bandwidth will depend on the system ram speed which can be up to 1866MHz (the max speed supported by the CPU). Therefore, the max operating memory clock is 933MHz.
Its performance is slightly worse than Intel HD 4600 and only very slightly better than previous Radeon HD 7560D.
Radeon HD 6450 is an entry-level 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 Caicos PRO which has 2 Compute Units activated and thus offers 160 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit Operates at 625MHz.
The GPU accesses a 512MB frame buffer of fast GDDR5, through a 64-bit memory interface. The memory clock operates at 800MHz. The size of the frame buffer is adequate.
DirectX 11.0 Support (11.0 Hardware Default) and support for HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.
The Cooling Solution consists of a Single-Fan.
With a rated board TDP of 18W, 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 only slightly below of a GeForce GT 520.
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with Radeon HD 6450.
