In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7870 PCS+ Vortex II Edition are massively better than the AMD Radeon HD 4830 HIS Fan 512MB Edition.

The HD 7870 has a 575 MHz higher core clock speed and 48 more Texture Mapping Units than the HD 4830. This results in the HD 7870 providing 73.6 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 7870 has a 575 MHz higher core clock speed and 16 more Render Output Units than the HD 4830. This results in the HD 7870 providing 27.6 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 HD 7870 was released over three years more recently than the HD 4830, and so the HD 7870 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 4830 when running the latest games.

The HD 7870 has 1536 MB more video memory than the HD 4830, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7870 also has superior memory performance overall.

The HD 7870 has 102.4 GB/sec greater memory bandwidth than the HD 4830, which means that the memory performance of the HD 7870 is massively better than the HD 4830.

The Radeon HD 4830 HIS Fan 512MB Edition has 640 Shader Processing Units and the Radeon HD 7870 PCS+ Vortex II Edition has 1280. However, the actual shader performance of the HD 4830 is 258 and the actual shader performance of the HD 7870 is 1251. The HD 7870 having 993 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7870 delivers a massively smoother and more efficient experience when processing graphical data than the HD 4830.

The HD 7870 transistor size technology is 27 nm (nanometers) smaller than the HD 4830. This means that the HD 7870 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4830.

The Radeon HD 4830 HIS Fan 512MB Edition requires 95 Watts to run but there is no entry for the Radeon HD 7870 PCS+ Vortex II Edition. We would recommend a PSU with at least 450 Watts for the HD 4830 and a PSU with at least 500 Watts for the HD 7870. The HD 7870 has been recommended a PSU with 50 Watts more than the HD 4830. The difference is significant enough that the HD 7870 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 4830.

GPU Mini Review

Mini ReviewOverview
Radeon HD 4830 HIS Fan 512MB Edition is a special edition of AMD's Performance Radeon HD 4830, created by HIS.

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

Overclock: Memory Clock
The Operating Memory Clock and the Frame Buffer remain the same.

Cooling Solution
The Cooling System consists of HIS' Fan which is Faster, Cooler and Quieter.

Performance
Without Overclocking Out of The Box, Radeon HD 4830 HIS Fan 512MB Edition is as fast as the reference Radeon HD 4830.
Radeon HD 7870 PCS+ Vortex II Edition is a special edition of Radeon HD 7870.
This is one of today's most powerful editions of the reference as it features increases in both the core and memory clocks that went from 1000MHz to 1150MHz and from 1200MHz to 1250MHz.
Benchmarks indicate the performance boost is quite extreme and around 8% when compared to the reference Radeon HD 7870.
