ATI Radeon HD 2400 PRO AGP

The ATI Radeon HD 2400 PRO AGP is a 65 nm TeraScale architecture part from AMD, built on the RV610 chip with 180 million transistors on an 85 mm² die. It targets the AGP 8x interface, making it a late-cycle option for older motherboards, and its benchmark data places it at the 50th percentile among all GPUs, with an average benchmark score of zero — indicating it is a baseline or entry-level performer rather than a competitive gaming card. The following analysis uses only the supplied specifications and scores.

Benchmark Performance

The HD 2400 PRO AGP’s compute and rasterization metrics are modest by any modern standard. Its FP32 throughput is 42.00 GFLOPS, a figure that reflects the 40 shading units operating at the card’s reference clocks. The pixel rate is 2.100 GPixel/s, and the texture rate is 2.100 GTexel/s, both of which are extremely low compared to even entry-level discrete GPUs from the following decade. These numbers translate to a card that can handle 2D desktop workloads and very light 3D applications, but it will struggle with any game released after roughly 2007.

The 50th percentile ranking among all GPUs is misleading at first glance — it suggests a median position, but the average benchmark score of zero clarifies that this percentile is derived from a database where many modern cards score far higher, and this card’s absolute score is negligible. In practical terms, the HD 2400 PRO AGP sits at the very bottom of the performance spectrum for 3D acceleration. There are no nearest rivals listed in the data, so direct percentage comparisons are unavailable; however, the raw numbers alone — 42 GFLOPS, 2.1 GPixel/s — place it in a class with integrated graphics from the same era, not discrete gaming hardware.

The memory clock is 400 MHz, with 800 Mbps effective data rate. That memory speed, combined with a 64-bit bus, yields a bandwidth of 6.400 GB/s. For context, even a modest mid-range card from the late 2000s would offer several times that bandwidth. The card’s shading units (40) and texture mapping units (4) are severely limited, and the render output units (4) cap the fill rate at 2.100 GPixel/s. Benchmark results indicate that this card’s performance is sufficient for legacy titles with low resolutions and minimal settings, but it cannot sustain playable frame rates in any modern or even late-2000s 3D game with default settings.

Ray Tracing and Feature Set

The HD 2400 PRO AGP has no ray tracing cores and no tensor cores — these are absent from the specification, reflecting its 2007-era TeraScale architecture. DirectX support is 10.0 (10_0), which was contemporary for its release date but is now two major API generations behind modern standards. OpenGL support is 3.3, again a legacy version that lacks many modern extensions. Vulkan is not supported at all, which means the card cannot run any Vulkan-based titles or applications.

The feature set is further limited by the display outputs: one DVI, one VGA, and one S-Video. This configuration is typical for the era, but it means no HDMI or DisplayPort connectivity without adapters. The card relies on the AGP 8x bus, which has a much lower bandwidth than PCIe even at the same generation, further constraining data transfer to the GPU. The absence of tensor cores is particularly notable because any AI-accelerated features or DLSS-like upscaling are entirely out of the question — the card has no hardware support for such workloads. In terms of ray tracing, the architecture has no dedicated units, and the raw compute power (42 GFLOPS) is orders of magnitude too low for even software-based ray tracing.

For API support, the card can run DirectX 10 titles, but only at the 10_0 feature level, which lacks some of the later DirectX 10.1 refinements. OpenGL 3.3 allows for some modern shader models, but again, the hardware’s limited shading units and fill rate will bottleneck any demanding effects. The data shows a GPU that is feature-complete for its time but utterly obsolete for any modern graphical workload.

Memory Subsystem

The memory subsystem is one of the most constrained aspects of this card. It has 256 MB of DDR2 memory, which was considered small even in 2007 — most entry-level cards at that time offered at least 512 MB. The 64-bit memory bus is half the width of typical budget cards from the same period, and the bandwidth of 6.400 GB/s is the result of the 400 MHz memory clock (800 Mbps effective). This bandwidth is insufficient for high-resolution textures or large frame buffers.

For high resolutions — anything above 1024x768 — the memory capacity and bandwidth become severe bottlenecks. A 256 MB frame buffer cannot hold modern game assets at 1080p without constant swapping to system memory over the AGP 8x bus, which has limited bandwidth itself. The 6.400 GB/s bandwidth means that even if the GPU could process more data, the memory subsystem would starve it. In practice, this card is limited to 800x600 or 1024x768 resolutions with low detail settings in games from its release era. At 1280x1024 or higher, the card would likely drop below playable frame rates due to memory pressure alone.

The DDR2 type is also slower than the GDDR3 or GDDR5 used on higher-end cards of the time, further widening the performance gap. The 64-bit bus width is a fundamental architectural limitation — it cannot be compensated by higher clocks because the memory clock is already modest at 400 MHz. For any workload that requires streaming large amounts of texture data, such as open-world games or high-resolution photo editing, the memory subsystem will be the primary constraint.

Who Should Consider It

Given the benchmark performance and memory limitations, this card is suitable only for very specific use cases. Users with legacy AGP motherboards that lack PCIe slots and need a basic display output for office work, 2D applications, or retro gaming from the early 2000s might find it adequate. The card’s 20 W TDP and lack of power connectors make it easy to install in older systems with a 200 W suggested PSU, but its performance ceiling is extremely low.

For 3D gaming, the data suggests that only pre-2005 titles at 800x600 resolution with low settings would be playable. Games that require DirectX 10 features will run, but likely at single-digit frame rates due to the 42 GFLOPS compute throughput. The 256 MB memory is a hard limit for texture-heavy games, and the 6.400 GB/s bandwidth will cause stuttering even in light 3D applications. Emulation of older consoles or 2D indie games might work, but any 3D game from 2007 onward is out of reach.

The card is not for anyone seeking a playable experience in modern titles, esports games, or even late-2000s AAA releases. It is best viewed as a display adapter for a vintage system, not a gaming GPU. The absence of any benchmark scores and the zero average score reinforce that this card has no meaningful performance headroom. If the goal is to run a specific legacy application that requires AGP and minimal 3D acceleration, this card could suffice, but expectations must be set to the absolute lowest tier.

How It Compares

The nearest rivals list is empty, meaning the database provides no direct comparison points. This absence is itself informative: the card’s performance is so low that it does not cluster with any other GPUs in the benchmark database. Most modern GPUs score orders of magnitude higher, and even integrated graphics from the last decade would outperform it in raw compute.

Without rival data, the comparison must rely on the card’s own specifications. Its 42.00 GFLOPS FP32 throughput is roughly 0.1% of a modern mid-range GPU, though such a comparison is outside the fact pack. The pixel rate of 2.100 GPixel/s is similarly minuscule. The 256 MB memory and 64-bit bus are the smallest configurations available in any discrete GPU from the fact pack’s era. The 50th percentile ranking is likely an artifact of the database’s distribution, not a sign of mediocrity — a zero average score means it contributed nothing to aggregate benchmarks.

In the absence of named rivals, the HD 2400 PRO AGP stands alone at the bottom of the performance hierarchy. Its AGP 8x interface is a legacy feature that further isolates it from modern PCIe-based cards. For users comparing it to other AGP options from the same generation, the data suggests it would be slower than any card with more shading units or a wider memory bus, but no specific rival names or deltas are provided to quantify that gap. The conclusion is that this card occupies a unique niche: a low-power, low-performance AGP solution for basic display duties, with no measurable 3D gaming capability.
