Redefine HD Gaming
With more than twice the processing power of previous generation AMD discrete graphics cards, ATI Radeon HD 4800 Series graphics cards deliver a cinematic gaming experience and unprecedented performance.
The new TeraScale graphics engine combines the power of up to 1.2 teraFLOPS, up to 800 stream processors and next generation GDDR5 memory to propel you deep into your gameplay with seamless frame rates and high resolutions.
Enhanced anti-aliasing (AA) and anisotropic filtering create striking graphics with unparalleled realism so you can max out the settings of the most demanding next-generation games or revitalize your favorite titles.
Play today while preparing for tomorrow with tessellation, support for DirectX 10.1 and scalable ATI CrossFireX technology.
Go Beyond HD Video
Add an ATI Radeon HD 4800 Series graphics card to your PC and watch the latest Blu-ray and HD movies play with incredible fidelity1 – upscale to nearly twice the display resolution of HD content.2 Take full advantage of Blu-ray functionality with dual-stream, picture in picture (PIP) capabilities.
Sophisticated new features within ATI Avivo HD technology give you the freedom and flexibility to edit videos quickly and convert them to H.264 and MPEG-2 formats 1.8x faster than real-time.3
Support for the latest audio visual interconnects ensures you can take advantage of the latest display technology.
Break-through Efficiency
Like their predecessors, the ATI Radeon HD 4800 Series graphics cards offer optimal performance and break-through efficiency with platform-independent intelligent power management.
Regardless of platform, these graphics cards deliver the power needed to blaze through even the most intense games while intuitively conserving energy at idle or when demand is low.
Review By Hothardware
Since the RV770 GPU’s initial arrival, we have seen the technology used in the GPU migrate up and down AMD’s product stack. At first, the RV770 powered only the ATI Radeon HD 4850 and 4870, but soon thereafter two RV770’s were linked together to form the current flagship Radeon HD 4870 X2. Then the GPU was scaled down to bring out the Radeon HD 4600, 4500, and 4300 series of products. Ultimately, AMD ended up with competitive offerings at virtually every price point, ranging from $39 on up, to over $550 for the flagship product. But there is an approximate $80 price gap between the $160-ish Radeon HD 4850 and the roughly $80 Radeon HD 4670, that AMD plans to fill today with the release of the Radeon HD 4830.

The HD 4830 supports DirectX 10.1 (DX10.1), though virtually all games use only DX10 features. The 3D performance is very good, falling just a few frames per second (fps) behind the more expensive HD 4850 in most of our tests. The DX9 F.E.A.R., for instance, clocked in at a playable 43fps at a massive 2,560×1,600 resolution, compared with 46fps for the HD 4850. The DX10 version of Company of Heroes was a speedy 53.7fps at 1,280×1,024 and a quite playable 32.5fps at 1,920×1,200, only slightly slower than the 54.1fps and 35.6fps results, respectively, for the HD 4850.

The Radeon HD 4830 variant is this same chip with two of those SIMD units disabled, leaving you 640 stream processors and 32 texture management units. The core clock speed has also been reduced to 575MHz (from 625MHz for the 4850) and the memory speed to 900MHz (from 1GHz). That’s a little less than 10% reduction in core clock speed and exactly 10% reduction in memory clock speed, along with a 20% reduction in stream processors and texture units.

Review By Bit-tech
The reference card comes clocked at 575MHz core and the memory is running at 1,800MHz (effective) – these are 50MHz and 200MHz lower than the ATI Radeon HD 4850’s reference speeds. Theoretically, then, the Radeon HD 4830 in its reference form is more than just 25 percent slower than the Radeon HD 4850 – it packs 736 GigaFLOPS of compute power, compared to the 1,000 GigaFLOPS (or one TeraFLOPS) of horsepower in the Radeon HD 4850.

Review By Legitreviews
When you compare the specifications on the three single GPU Radeon HD 4800 series cards you can see how they stack up across the board. Notice that the max board power remains the same on the Radeon HD 4830, so power consumption and temperatures should be close to what is seen on the Radeon HD 4850 graphics card. The clock rate on the Radeon HD 4830 is 575MHz with the memory clock being 900MHz. The Radeon HD 4830, 4850 and 4870 all have 956 Million transistors and are built on the 55nm process.
