About ATI Radeon X800 XT
The ATI Radeon X800 XT is a legacy, end-of-life graphics card built on the 130 nm process at TSMC, featuring the R423 chip and the R400 architecture. It targets the PCIe 1.0 x16 interface, a transition point in the early 2000s, and is positioned for users running older DirectX 9.0b applications. Its performance profile, defined by a 50th percentile rank among all GPUs, places it in the absolute middle of the historical performance spectrum, making it unsuitable for any modern workload but relevant for period-specific retro builds. The card offers a fixed set of hardware capabilities: 16 texture mapping units and 16 render output units, delivering a pixel rate of 8.000 GPixel/s and a texture rate of 8.000 GTexel/s. With 256 MB of GDDR3 memory on a 256-bit bus, it achieves a bandwidth of 32.00 GB/s, which was substantial for its era but minuscule by current standards.
Who Should Consider It
The benchmark data shows that the X800 XT is a strictly retro-oriented product. Its 50th percentile ranking across all GPUs means that half of all graphics cards ever benchmarked perform better, and half perform worse. This is not a card for modern gaming at any resolution. For users with a period-correct system from 2004-2005, the card is suitable for running contemporary titles at 1024x768 or 1280x1024 resolutions, where its 8.000 GPixel/s fill rate and 32.00 GB/s bandwidth were sufficient for the era's DirectX 9.0b games. However, at higher resolutions like 1600x1200, the 256 MB frame buffer and 32.00 GB/s memory bandwidth would become limiting factors, causing texture thrashing and stuttering in memory-intensive scenes. The card's 16 TMUs and 16 ROPs are balanced for the shader complexity of early 2000s games, but they cannot handle modern geometry or shading workloads. For emulation or legacy software, the X800 XT is a competent choice, but it has zero utility for cloud gaming, productivity, or any current API workload, as its highest supported DirectX version is 9.0b (9_2). The data indicates that this card should only be considered by collectors or builders creating authentic early-PCIe-era systems, and even then, the 50th percentile position suggests it was a mid-pack performer, not a flagship.
Ray Tracing and Feature Set
The X800 XT has no ray tracing capability whatsoever. The FACT PACK lists no RT cores and no tensor cores, confirming that hardware-accelerated ray tracing and AI-based features like DLSS are entirely absent. The card's feature set is anchored to the DirectX 9.0b (9_2) API, which is a pre-shader-model-3.0 specification. This means the card cannot run games that require Shader Model 3.0 or later, limiting its software compatibility to a narrow window of titles released between 2002 and 2004. On the API front, it supports OpenGL 2.1, which provides some measure of compatibility with legacy Linux or professional applications, but Vulkan support is null, cutting off any modern cross-platform graphics API access. The absence of tensor cores means no deep learning super sampling, and the lack of RT cores means no dedicated ray tracing hardware. The card's 16 TMUs handle texture filtering, and its 16 ROPs manage pixel output, but there are no specialized units for compute or geometry processing beyond what the R400 architecture provided in its fixed-function pipeline. For users seeking any modern feature set, this card is a dead end. The display outputs—1x DVI, 1x VGA, and 1x S-Video—reflect the connectivity standards of 2004, with no support for HDMI, DisplayPort, or any digital audio passthrough, further cementing its status as a museum piece.
Power and Cooling
The power profile of the X800 XT is modest by modern standards but was significant for its time. The card has a thermal design power (TDP) of 54 W, which is low enough to be handled by a single-slot cooling solution, as indicated by its single-slot form factor. The recommended power supply is 250 W, a figure that aligns with typical mid-range PC builds from the mid-2000s. Power is delivered via a single 6-pin PCIe power connector, which was a standard requirement for higher-end cards of that generation. The 54 W TDP means that the card does not generate excessive heat, and a capable air cooler with a single slot should suffice for maintaining operational temperatures in a well-ventilated case. However, users should note that the 250 W PSU recommendation is for the entire system, and pairing this card with a high-end CPU from 2004 could strain that budget. The card's power connectors (1x 6-pin) are a strict requirement; attempting to run it without the auxiliary power connection would likely result in instability or failure to post. The single-slot design also means that adjacent PCIe slots remain usable, which is an advantage for systems with multiple expansion cards. The low TDP relative to later flagship cards (which exceeded 100 W) allowed for quieter operation, but the data shows no specific noise or thermal throttling metrics, so qualitative assessment is limited to the slot width and TDP figures provided.

How It Compares
The FACT PACK lists no nearest rivals for the ATI Radeon X800 XT, meaning there is no direct comparative benchmark data against other specific GPUs. The card's percentile rank of 50 against all GPUs establishes a baseline: it sits exactly at the median of the entire historical database of graphics cards. This is a stark indicator of its age and performance ceiling. Without rival scores, one cannot state specific deltas or percentage leads, but the 50th percentile implies that half of all GPUs ever tested are faster, including every integrated solution from the last decade and all discrete cards from the past fifteen years. The absence of rivals in the data suggests that the card's performance class is so distinct from modern entries that no meaningful comparison can be drawn. For context, its successor, the Radeon R500 PCIe, would represent a generational leap, while its predecessor, the Radeon R300, was the foundational architecture. The X800 XT's 54 W TDP and single-slot design are conservative, but its 8.000 GPixel/s and 8.000 GTexel/s rates are fixed hardware limits that no driver update can overcome. The card's 32.00 GB/s bandwidth is a hard constraint, and the 256 MB memory capacity is insufficient for any texture-heavy workload beyond 2004-era titles. In the absence of rival data, the analysis must rely on absolute values: the 50th percentile rank, the API limitations, and the memory size all paint a clear picture of a card that was mid-range at launch and is now obsolete.
