About ATI Radeon HD 4850 X2
The ATI Radeon HD 4850 X2 is an end-of-life graphics card from AMD, built on the TeraScale architecture and the R700 chip. It was released on November 6, 2008, and is manufactured on a 55 nm process at TSMC, with 956 million transistors on a 256 mm² die, yielding a transistor density of 3.7 million per square millimeter. The card features 800 shading units, 40 texture mapping units, and 16 ROPs, with peak rates of 1,000 GFLOPS FP32 compute, 25 GTexel/s texture fill, and 10 GPixel/s pixel fill. Its memory subsystem comprises 512 MB of GDDR3 on a 256-bit bus, delivering 63.68 GB/s of bandwidth at a memory clock of 995 MHz (1990 Mbps effective). The card draws up to 250 W, requires a 600 W power supply, and uses one 6-pin and one 8-pin PCIe power connector. Its launch MSRP was 420 USD.
Benchmark Performance
The database does not list any benchmark scores for the HD 4850 X2. The average benchmark score is recorded as 0, and the percentile rank against all GPUs is 50, meaning the card sits exactly at the median of the distribution. Without nearest-rival data or sample scores, percentage deltas cannot be computed. However, the theoretical peak rates provide a baseline: 1,000 GFLOPS of FP32 compute, 25 GTexel/s of texture throughput, and 10 GPixel/s of pixel fill. These figures indicate a card capable of substantial arithmetic and fill-rate work, but the lack of comparative scores prevents a definitive performance tier placement. The 50th percentile suggests that, among all GPUs in the database, this card outperforms half and underperforms the other half, yet that rank is not tied to a measurable benchmark outcome. The absence of rival entries further limits any positional analysis; the data simply shows a mid-pack standing with no direct competitors identified.
Ray Tracing and Feature Set
The specifications list no RT cores and no tensor cores, indicating the hardware does not include dedicated ray tracing or tensor processing units. API support is limited to DirectX 10.1 (feature level 10_1) and OpenGL 3.3; Vulkan is not listed. This combination shows the card is designed for traditional rasterization workloads within the DirectX 10.1 and OpenGL 3.3 feature sets. The absence of Vulkan support and the lack of any ray tracing hardware mean the card cannot handle modern API-based effects or compute tasks that rely on those features. The TeraScale architecture, as reflected in the R700 chip, focuses on fixed-function and shader-based rendering, with no provisions for hardware-accelerated ray tracing or AI-based upscaling. Users requiring those capabilities would need to look elsewhere, but for DirectX 10.1 titles, the feature set is adequate.
Memory Subsystem
The HD 4850 X2 is equipped with 512 MB of GDDR3 memory, a capacity that is modest even by 2008 standards. The 256-bit memory interface, combined with a memory clock of 995 MHz (1990 Mbps effective), yields a bandwidth of 63.68 GB/s. This bandwidth is sufficient for 1080p gaming with moderate texture quality, but the small frame buffer may become a limiting factor when high-resolution textures or multi-sample anti-aliasing are enabled. The pixel rate of 10 GPixel/s and texture rate of 25 GTexel/s suggest the card can handle fill-rate-intensive scenes at lower resolutions, but the memory capacity could cause stuttering or texture swapping in memory-heavy scenarios. The effective 1990 Mbps memory speed is a standard figure for GDDR3 of that period, and the 63.68 GB/s bandwidth aligns with the 256-bit bus width. For users targeting 720p or 1080p with reduced texture settings, the memory subsystem is adequate; for higher resolutions or large texture packs, the 512 MB limit will be apparent.
How It Compares
The database provides no nearest rivals for the HD 4850 X2. As a result, direct comparisons to specific competing GPUs are not possible. The card's 50th percentile rank across all GPUs places it at the median, but without rival scores, we cannot determine how it stacks up against particular models. The absence of benchmark data further limits any comparative analysis. The only positional information is the percentile rank, which suggests a middle-of-the-road performance level among all recorded devices. Without a named rival list, any attempt to quantify deltas or advantages would be speculative. The data simply does not support a comparative narrative, and the card's standing must be interpreted from its absolute specifications alone.

Power and Cooling
The HD 4850 X2 has a TDP of 250 W, a substantial power draw for a card released in 2008. The suggested power supply is 600 W, and the card requires one 6-pin and one 8-pin PCIe power connector to deliver that wattage. The card occupies a dual-slot form factor, which is typical for high-end GPUs of its generation, and measures 267 mm in length (10.5 inches). The dual-slot design provides a larger heatsink and fan assembly to dissipate the 250 W of heat generated under load. The power connector configuration—one 6-pin and one 8-pin—is standard for cards in this power class, ensuring adequate current delivery from the PSU. Users must verify their power supply has both connector types and sufficient capacity to meet the 600 W recommendation. The dual-slot footprint also means the card will cover adjacent expansion slots on the motherboard, a consideration for system builders with limited space.
Who Should Consider It
The HD 4850 X2 is suited for 1080p gaming with moderate detail settings, given its 1,000 GFLOPS FP32 compute and 25 GTexel/s texture rate. The 512 MB frame buffer, however, is a limiting factor for high-resolution textures, and the 63.68 GB/s bandwidth may become a bottleneck in memory-intensive scenes. The card's DirectX 10.1 support makes it compatible with games that use that API, but titles requiring DirectX 11 or Vulkan will not run with full feature sets. The lack of ray tracing and tensor cores precludes any modern effects that rely on those hardware units. For users who play older DirectX 10.1 titles at 720p or 1080p with reduced texture quality, this card offers adequate performance. The 50th percentile rank indicates a median position among all GPUs, but without benchmark scores, a more precise recommendation cannot be made. Those seeking high-resolution texture detail or advanced API features should consider other options, as the 512 MB capacity and limited API support are significant constraints.
