Clock speeds directly impact the ATI Radeon HD 2600 XT AGP's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The ATI Radeon HD 2600 XT AGP by AMD dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
AMD's ATI Radeon HD 2600 XT AGP Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The ATI Radeon HD 2600 XT AGP's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.
ATI Radeon HD 2600 XT AGP by AMD Cache
On-chip cache hierarchy
On-chip cache provides ultra-fast data access for the ATI Radeon HD 2600 XT AGP, reducing the need to fetch data from slower VRAM.

About ATI Radeon HD 2600 XT AGP
The ATI Radeon HD 2600 XT AGP is an end-of-life graphics card from AMD, built around the RV635 chip. It uses the TeraScale architecture and belongs to the Radeon R600 generation. TSMC fabricated the chip on a 55 nm process; the die measures 135 mm² and contains 378 million transistors, for a transistor density of 2.8M / mm². The card carries 256 MB of DDR2 memory on a 128-bit bus and connects through AGP 8x. It was released on 2007-06-27, positioned between the Radeon R500 PCIe and the Radeon R700 in the product sequence. In this database it holds a 50th percentile rank among all GPUs and an average benchmark score of 0.
How It Compares
The nearestRivals array in the FACT PACK is empty. That means there are no rival names, rival scores, or deltaPct values available to cite. As a result, this section cannot provide the usual product-by-product comparison paragraphs. The only positional signal is the percentileVsAllGpus field, which is 50. A 50th percentile rank places the card at the median of the GPU distribution in the database: half of all GPUs rank above it and half rank below it.
The average benchmark score is 0, and the benchmarks array is also empty. There is therefore no numerical benchmark evidence to separate this card from any other product. The predecessor and successor fields give context—Radeon R500 PCIe before it, Radeon R700 after it—but they are not measurement data. Any statement comparing this card to a specific rival in percentage terms would require the nearestRivals entries, and those entries are absent from the record.
Memory Subsystem
The memory subsystem is built around 256 MB of DDR2 memory on a 128-bit bus. The memory clock is 405 MHz, with an 810 Mbps effective data rate. Those figures produce a peak memory bandwidth of 12.96 GB/s.
For high-resolution workloads, this configuration is restrictive. A 256 MB frame buffer is small; once textures, geometry buffers, and render targets exceed that capacity, data must be moved on and off the card. The 12.96 GB/s bandwidth is the ceiling for that movement, so scenes with large texture sets are likely to be constrained by the memory system. The 128-bit bus also limits the amount of data that can cross per clock. The memory figures in the record define a card that is better suited to lower resolutions and reduced texture detail than to high-resolution, high-fill workloads.
The pixel rate further reinforces this. With 4 ROPs, the card’s pixel fill rate is 2.888 GPixel/s. Texture fill rate is 5.776 GTexel/s. These rates matter when resolution rises, because more pixels must be written per frame. Combined with the memory limitations, the data points toward a card that performs within a modest envelope rather than a high-end frame buffer.
Who Should Consider It
The bus interface is AGP 8x, so this card is aimed at systems with an AGP slot rather than a PCIe slot. The predecessor listed in the record is the Radeon R500 PCIe, which suggests this product was designed to serve as an upgrade path for AGP-based motherboards. The 45 W TDP and the 200 W suggested PSU further indicate that it is intended for modest system power budgets. The single-slot design keeps the physical footprint small, which helps in compact chassis.
The memory configuration and the 50th percentile ranking align on a practical recommendation: this is not a card designed for high-resolution, high-detail gaming. With 256 MB of DDR2 memory and 12.96 GB/s of bandwidth, users should plan on lower resolutions and reduced texture settings. The absence of benchmark scores means the database cannot verify specific settings for specific applications. Given the end-of-life production status, the card is best considered as a drop-in part for an older AGP system, not as the foundation of a new build. Users who need a high-rank GPU in the current database should look elsewhere; the data here shows a mid-pack product.

Benchmark Performance
The benchmark data in this record is very limited. The benchmarks array is empty, and the average benchmark score is 0. The nearestRivals list is also empty, so no deltaPct values or rival scores exist to analyze. Without those fields, exact percentage comparisons against other GPUs are not possible.
The only ranked figure is percentileVsAllGpus at 50. That places the card exactly at the median of the database’s GPU distribution. This is a neutral position: it indicates that the card is neither a top-tier performer nor a bottom-tier one, but it does not explain why. The percentile rank cannot be converted into a percentage lead or deficit in this record because the distribution data and rival performance values are not supplied.
The listed theoretical rates provide some idea of the silicon’s limits. The card has 120 shading units, 8 texture mapping units, and 4 ROPs. Pixel fill rate is 2.888 GPixel/s, texture fill rate is 5.776 GTexel/s, and FP32 compute is 173.3 GFLOPS. These are peak capacities, not actual benchmark scores. They represent upper bounds, assuming no memory bottleneck. Given the memory subsystem’s 12.96 GB/s bandwidth, sustained performance in real workloads will likely fall below those theoretical peaks.
Because no core clock is listed in the FACT PACK, clock-based analysis is also impossible. The record contains only the memory clock. In short, the benchmark section of this database entry is defined by one median percentile and a zero average score. There is no rival deltaPct data to support a claim of being ahead of or behind any specific product.
Power and Cooling
The card has a TDP of 45 W, a modest power figure for the product class. The suggested PSU rating is 200 W, and the card requires 1x 6-pin power connector. That connector must be available from the system power supply, even though the overall system recommendation is low.
The physical design is single-slot, meaning the card occupies only one expansion slot. No cooler dimensions are included in the FACT PACK, so the single-slot width and the 45 W TDP are the only thermal design signals available. The 45 W TDP suggests that a compact cooling solution can handle the heat output. The 200 W PSU recommendation is a system-level figure; it indicates the card is not designed for large multi-GPU or high-wattage setups.
The AGP 8x interface is the other important power and installation consideration. This is not a PCIe card; it requires a motherboard with an AGP slot. The combination of AGP 8x, single-slot width, 45 W TDP, and a 200 W suggested PSU makes the card suitable for older systems with limited power delivery and physical space. All power figures in this section come directly from the FACT PACK: 45 W, 200 W, and 1x 6-pin.
