In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4830 512MB are noticeably better than the AMD Radeon R7 240 2GB.

The R7 240 has a 155 MHz higher core clock speed than the HD 4830, but the HD 4830 has 12 more Texture Mapping Units than the R7 240. As a result, the HD 4830 exhibits a 3.8 GTexel/s better Texture Fill Rate than the R7 240. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 240 has a 155 MHz higher core clock speed than the HD 4830, but the HD 4830 has 8 more Render Output Units than the R7 240. As a result, the HD 4830 exhibits a 3.4 GPixel/s better Pixel Fill Rate than the R7 240. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 240 was released over three years more recently than the HD 4830, and so the R7 240 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 R7 240 has 1536 MB more video memory than the HD 4830, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the HD 4830 has superior memory performance.

The HD 4830 has 28.8 GB/sec greater memory bandwidth than the R7 240, which means that the memory performance of the HD 4830 is slightly better than the R7 240.

The Radeon R7 240 2GB has 320 Shader Processing Units and the Radeon HD 4830 512MB has 640. However, the actual shader performance of the R7 240 is 212 and the actual shader performance of the HD 4830 is 258. The HD 4830 having 46 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 4830 delivers a noticeably smoother and more efficient experience when processing graphical data than the R7 240.

The R7 240 transistor size technology is 27 nm (nanometers) smaller than the HD 4830. This means that the R7 240 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4830.

The Radeon R7 240 2GB requires 30 Watts to run and the Radeon HD 4830 512MB requires 95 Watts. We would recommend a PSU with at least 400 Watts for the R7 240 and a PSU with at least 450 Watts for the HD 4830. The HD 4830 requires 65 Watts more than the R7 240 to run. The difference is significant enough that the HD 4830 may have an adverse affect on your yearly electricity bills in comparison to the R7 240.

GPU Mini Review

Mini ReviewNote: This Graphics Card has 2 variants: one with DDR3 and another with GDDR5. This is the DDR3 Version.

Radeon R7 240 2GB offers a core codenamed Oland PRO and thus features 320 Shader Processing Units, 20 TMUs and 8 ROPs, on a 128-bit bus width of standard DDR3. While the central unit runs at 730MHz and goes up to 780MHz, in Turbo Mode, the memory clock operates at 900MHz.
With a rated board TDP of 30W, it requires no extra power connectors.

Compared to Radeon R7 250, its performance is significantly lower (over 25% slower), especially at higher resolutions due to the limited memory bandwidth. Still, the TDP is relatively low and so this card may be used on low end systems and offer a reasonable upgrade, when compared to integrated graphics.
Radeon HD 4830 is a high-end GPU based on the 55nm, third unified shader architecture, R700.
It's based on the RV790 LE Core (related to Radeon HD 4860) and offers 640 Shader Processing Units, 32 TMUs and 16 ROPs a 256-bit memory interface of standard GDDR3. The central unit runs at 575MHz and the memory clock runs at up to 900MHz.
It performs much worse when compared to Radeon HD 4850/Radeon HD 4870 due to being paired with standard GDDR3, featuring less Shading Units & TMUs and being relatively underclocked. However, it's expected to consume only up to 95 Watt.
Some of today's modern games should run fluently at high settings but with modest resolutions. DirectX 11 games aren't supported.
