About ATI Radeon HD 2600 XT X2
The ATI Radeon HD 2600 XT X2 is a dual-GPU card from AMD, built on the 65 nm TSMC process with the RV630 chip, part of the TeraScale architecture. It packs 390 million transistors on a 153 mm² die, yielding a transistor density of 2.5M per mm². The card was released on 2007-07-25, sits at the 50th percentile among all GPUs in the database, and is now end-of-life, with the Radeon R700 as its successor and the Radeon R500 PCIe as its predecessor.
How It Compares
The nearestRivals list for this card is empty in the FACT PACK, so there are no direct rival names, scores, or deltaPct values to reference. This means the HD 2600 XT X2 cannot be positioned against specific competing products using the provided data. Benchmark results indicate that the card holds a median standing—exactly the 50th percentile—among all GPUs tracked, which places it in the middle of the pack historically. Without rival data, the practical takeaway is that this card was a mainstream offering in its era, not a performance flagship, and its relative standing must be inferred from its own specifications rather than head-to-head comparisons.
The absence of nearestRivals also means no percentage deltas can be computed for this card against any named competitor. The data shows a 50th percentile rank, which suggests that roughly half of all GPUs in the database outperform it and half underperform it, but the specific gap to any particular card remains undefined. For a builder looking at this card today, the lack of rival context reinforces that it is a legacy product, and any modern comparison would require external data not present in this analysis.
Memory Subsystem
The HD 2600 XT X2 comes with 512 MB of GDDR3 memory on a 128-bit bus, running at 800 MHz with 1600 Mbps effective data rate. This configuration yields a memory bandwidth of 25.60 GB/s. For its time, 512 MB was a common capacity for mid-range cards, but the 128-bit bus is narrow by modern standards, and the resulting bandwidth is modest. At high resolutions, such as 1600x1200 or beyond (though no specific resolution is cited in the FACT PACK), the 25.60 GB/s figure would likely become a bottleneck, especially in texture-heavy scenes where the GPU must fetch data quickly. The pixel rate of 3.200 GPixel/s and texture rate of 6.400 GTexel/s further indicate that the card's fill rates are limited, which aligns with the memory bandwidth—this is a card designed for 1280x1024 or lower settings, not for pushing high pixel counts.
The 128-bit bus width means that each memory clock cycle transfers only 128 bits of data, which is half the width of higher-end cards of that generation. With GDDR3 at 1600 Mbps effective, the theoretical bandwidth calculation (bus width × effective clock / 8) yields exactly 25.60 GB/s. For a dual-GPU card, this shared memory subsystem is particularly important: both GPUs must access the same 512 MB pool, and the bandwidth is split between them. In practice, this could lead to contention when both GPUs are active, reducing effective throughput in multi-GPU scenarios. The data shows that this is a capacity and bandwidth-constrained design, suitable for 1080p-class gaming only with reduced detail levels.
Ray Tracing and Feature Set
This card does not have any dedicated ray tracing cores or tensor cores—those fields are null in the FACT PACK. The HD 2600 XT X2 relies entirely on its 120 shading units for all compute and graphics work. It supports DirectX 10.0 (10_0) and OpenGL 3.3, but has no Vulkan support. The absence of Vulkan is notable because it means the card cannot leverage modern low-level APIs that are common in current games and applications. DirectX 10.0 was introduced with Windows Vista and represented a step forward in shader model 4.0, but it is now several generations behind. Ray tracing is entirely unsupported at the hardware level, so any ray-traced effects would be impossible or would fall back to software, which would be impractically slow given the 192.0 GFLOPS of FP32 compute.
The feature set is firmly rooted in the mid-2000s. The 120 shading units, 8 texture mapping units, and 4 ROPs define a GPU that was aimed at mainstream DirectX 10 gaming, not at advanced features like variable rate shading, mesh shaders, or hardware-accelerated ray tracing. The card does support 4x DVI and 1x S-Video outputs, which reflects the display technology of its era—multi-monitor setups were possible, but with analog or DVI connections rather than DisplayPort or HDMI, and no modern features like HDR or adaptive sync are present in the data. For a current buyer, the feature set is a limitation, but for a retro build, it is historically authentic.

Benchmark Performance
The FACT PACK lists no benchmark scores for this card, and the avgBenchmarkScore is 0, so there are no absolute performance numbers to analyze. However, the percentileVsAllGpus field shows a value of 50, which means the card sits exactly at the median of all GPUs in the database. This is a meaningful datapoint: in a historical context, it indicates that the HD 2600 XT X2 outperformed half of all GPUs ever tracked and underperformed the other half. Given that this card was released in 2007, this 50th percentile rank is heavily influenced by the many older and weaker GPUs that predate it, as well as the newer, faster ones that followed. The dual-GPU design likely boosts its standing relative to the single-GPU HD 2600 XT, but without rival scores, no precise delta can be cited.
The compute figures provide further context: FP32 performance is 192.0 GFLOPS, with a pixel rate of 3.200 GPixel/s and a texture rate of 6.400 GTexel/s. These numbers are low by modern standards, but they were competitive in the 2007 mid-range segment. The 120 shading units at the listed clocks (memory at 800 MHz, though core clocks are not provided in the FACT PACK) would have handled DirectX 10 titles at moderate settings. The lack of any nearestRivals data prevents a direct percentage comparison, but the 50th percentile rank is the only benchmark-derived metric available, and it suggests a balanced, middle-of-the-road performance profile. In practical terms, this card would struggle with any modern game, but for its era, it delivered acceptable frame rates at lower resolutions and detail settings.
Power and Cooling
The card is a dual-slot design, meaning it occupies two expansion slots in a chassis, which is typical for a dual-GPU card with a larger cooler. It requires a single 6-pin power connector, and the suggested PSU rating is 200 W. The FACT PACK does not list a TDP value, so no exact power draw figure can be stated, but the 200 W suggested PSU indicates that the entire system should have at least that capacity—this is a conservative recommendation that accounts for the card plus other components. The 6-pin connector is a standard PCIe power input, and the dual-slot cooler suggests that heat dissipation is handled via a substantial heatsink and fan assembly, likely necessary given the dual RV630 chips.
The 65 nm process node and 390 million transistors contribute to a power profile that is modest by 2024 standards but was typical for a high-end card in 2007. Without a TDP number, the builder must rely on the 200 W PSU recommendation as the only concrete power guidance. The dual-slot form factor means that adjacent PCIe slots may be blocked, which is a practical consideration for system builders. The card uses a PCIe 1.0 x16 interface, which is forward-compatible with modern slots but may limit bandwidth on newer systems. Overall, the power and cooling requirements are straightforward: a 200 W PSU, one 6-pin cable, and enough case clearance for a dual-slot card. The absence of a TDP figure is a gap in the data, but the other specifications provide enough to plan a build around this legacy component.
