Sapphire Radeon HD 4650 HDMI 512MB video card review
25 March 2012
Conclusion: We've already marvelled somewhat at RV730 during our Radeon HD 4670 review, and how a GPU with as many Stream Processors as a last-generation high-end board can crop up at such a low price point, and that line of thought follows even more so with the Radeon HD 4650, which brings us the exact same GPU (at lower clock speeds, of course) at a sub-£60 price point if you shop around.
Excerpt: Sapphire Radeon HD4650 AGP Review Sapphire AGP is dead; Long Live AGP! In 1997, Intel created a new expansion path for improving performance of video display. The Accelerated Graphics Port offered a dedicated point-to-point 32-bit 66MHz pathway to the processor and a separate 8-bit sideband addressing method, which allowed the graphics controller to issue instructions to the processor without interrupting the data flow over the main 32-bit bus.
Conclusion: Despite the fact that an AGP slot has not been on motherboards in a long time we seem to still see these cards being made. As stated before, if you currently have a X1950 or higher then there is not really any reason to move to this chip. However if you are running on an older AGP chip, and find that your old graphics card just isnt playing games anymore will probably find the jump useful.
Conclusion: The first thing you have to look at before buying this card is the price. Though the card is cheaper than the HD 4670, is it really worth it? Now, if this were the difference between an HD 4850 and HD 4870, where the price difference is bigger, then you should put more thought into it. The downfall of the HD 4650 is the fact that you can buy an HD 4670 for the same price and have more performance.
Summary: If you are purely looking for the best bang for the buck in the ATI graphics card lineup then the HD 4650 and HD 4670 are definitely the best choice. While their 3D performance can certainly not rival high-end cards they are good for some pretty serious gaming.
What makes the Sapphire HD 4650 OC Edition very interesting is the enormous overclocking potential left in the card.
Pros: Phenomenal overclocking potential, Good price/performance ratio, Overclocked out of the box, Low power draw, DirectX 10.1 support
Cons: Very Noisy cooler, Low stock overclock, No support for CUDA/PhysX
