About ATI Radeon HD 2400 PRO
The ATI Radeon HD 2400 PRO is an entry-level graphics card from AMD's TeraScale architecture family, built on the RV610 chip at TSMC's 65 nm process. It carries 180 million transistors on an 85 mm² die, giving a transistor density of 2.1M per mm². The card targets basic desktop workloads rather than high-end gaming, and its percentile ranking of 50 against all tracked GPUs places it at the midpoint of the database. Released on 2007-06-27, it sits between the Radeon R500 PCIe generation and the later Radeon R700 series. The card is end-of-life, with no recorded benchmark scores.
Memory Subsystem
The HD 2400 PRO ships with 256 MB of DDR2 memory across a 64-bit bus. The memory clock runs at 400 MHz, which translates to 800 Mbps effective. Total bandwidth comes to 6.400 GB/s. That figure is modest, and it directly constrains the card's behavior at higher resolutions. A 64-bit bus combined with DDR2 means the memory controller delivers data in narrow bursts, so fill-rate-heavy workloads stall once the frame buffer exceeds what the card can feed.
For high resolutions, 256 MB of VRAM is a hard ceiling. Frame buffers for high-resolution textures and post-processing easily exceed this capacity, forcing the card to spill to system memory over the PCIe 1.0 x16 interface. That bus is an older generation, so the fallback path is slow. At lower resolutions with reduced texture detail, the memory subsystem can keep up with the card's compute capabilities, but the 6.400 GB/s bandwidth will still bottleneck any scene with heavy alpha blending or large render targets.
The pixel rate of 2.100 GPixel/s and texture rate of 2.100 GTexel/s are consistent with a 64-bit memory path. The card shades and textures roughly in lockstep with what the bus delivers. In practice, the HD 2400 PRO is best suited to lightweight 2D desktop work and older titles at low resolutions and detail settings. High-resolution gaming is not realistic given the VRAM and bandwidth constraints.
Ray Tracing and Feature Set
The HD 2400 PRO has no dedicated ray tracing cores and no tensor cores; both fields are null in the data. Ray tracing acceleration is not present in the hardware, so any ray-traced effects would run entirely in software, which the card's 42.00 GFLOPS of FP32 compute cannot handle at playable rates.
The feature set centers on API support rather than hardware acceleration. The card supports DirectX 10.0 with the 10_0 feature level, and OpenGL 3.3. Vulkan is not supported. The HD 2400 PRO's 40 shading units, 4 TMUs, and 4 ROPs are low counts, limiting texture fetch and pixel output throughput, but they match the card's positioning as a basic DirectX 10-capable part.
What this means in practice: the card can run DirectX 10 titles, but with 40 shaders and 4 ROPs, it will only manage playable frame rates at low resolutions and reduced settings. OpenGL 3.3 support allows compatibility with applications that rely on that API version. There is no Vulkan path, so Vulkan-only titles will not run. The absence of tensor and RT cores is not a deficiency for the era, but it does mean the card is unsuitable for any workload that depends on those features.
Who Should Consider It
The data positions the HD 2400 PRO at the 50th percentile of all GPUs tracked in the database, with no benchmark scores recorded. That percentile is a midpoint ranking, but the card's raw specifications tell a clearer story. With 256 MB of VRAM, 6.400 GB/s of bandwidth, and 42.00 GFLOPS of compute, this is a card for basic display output, not gaming or compute.
A user who needs a simple single-slot card for a legacy system with a PCIe 1.0 x16 slot, and who only requires DVI, VGA, or S-Video output, could consider the HD 2400 PRO. The three display outputs cover analog and early digital connections. The card draws only 20 W, so it will not stress a weak power supply. It is also end-of-life, so anyone building a new system today should look at the successor, the Radeon R700 series, or anything more modern.
For gaming, the HD 2400 PRO is only viable for titles from its own era at low settings. The 40 shading units and 4 ROPs cannot push modern geometry or shader complexity. The 256 MB frame buffer rules out high-resolution textures. If the goal is retro gaming with period-appropriate hardware, the card fits; if the goal is current titles or GPU-accelerated compute, it does not.

Benchmark Performance
The FACT PACK records no benchmark scores for the HD 2400 PRO, and the average benchmark score is listed as 0. The percentile versus all GPUs is 50, which places the card at the median of the database's tracked hardware. This is an unusual pairing: a median percentile with no actual benchmark entries suggests the card is ranked by its specifications and feature set rather than by measured performance.
Without nearestRivals data, there are no direct percentage deltas to cite against competing products. The card's own metrics provide the context. Its 42.00 GFLOPS of FP32 compute is the raw shader throughput, and its 2.100 GPixel/s pixel rate and 2.100 GTexel/s texture rate are the output limits. These figures are all low in absolute terms, consistent with an entry-level part.
The 40 shading units, 4 TMUs, and 4 ROPs form a balanced but minimal configuration. A 10:1:1 ratio of shaders to TMUs to ROPs means the card can shade far more than it can texture or rasterize, which is typical for a part where memory bandwidth is the primary constraint. The 6.400 GB/s bandwidth will throttle any workload that needs sustained data movement. In practical terms, the HD 2400 PRO will handle 2D desktop acceleration and very light 3D loads, but it will not deliver playable frame rates in any modern or demanding title.
The lack of benchmark data means there is no measured frame-rate evidence to analyze. The percentile of 50 is the only relative ranking available, and it should be read with caution given the empty benchmark array. The card's position in the database is based on its characteristics, not on tested performance.
Power and Cooling
The HD 2400 PRO has a TDP of 20 W, which is minimal. The suggested power supply is 200 W, meaning even a modest system PSU can drive this card. There are no power connectors on the card; it draws all its power from the PCIe 1.0 x16 slot. The single-slot design means it occupies only one expansion slot.
The 65 nm process from TSMC, with 180 million transistors on an 85 mm² die, keeps heat output low. A 20 W TDP does not require an auxiliary power connector, and the card's thermal footprint is small enough for compact or legacy systems. The PCIe 1.0 x16 interface is the only connection to the host, providing both data and power. Users upgrading an older system should verify that their motherboard has a PCIe x16 slot, since the card does not support other interfaces.
Cooling is straightforward: a single-slot cooler is sufficient. The card's end-of-life status means replacement coolers may be hard to find, but the low 20 W TDP keeps cooling requirements minimal. The 200 W suggested PSU is a guideline for the whole system, not just the card; a system with a power-hungry CPU will need more headroom, but the card itself adds only 20 W to the total draw.
