About ATI Mobility Radeon HD 4550
The ATI Mobility Radeon HD 4550 is an end-of-life mobile graphics processor from AMD, built on the TeraScale architecture using the M93 chip. Fabricated by TSMC on a 55 nm process, it integrates 242 million transistors into a 73 mm² die, achieving a transistor density of 3.3 million per square millimeter. It belongs to the M9x generation (Mobility HD 4500 series), succeeding the M8x and preceding the Manhattan generation. The card ships as an MXM Module with an MXM-II bus interface, and its display outputs are portable-device dependent. The database records an average benchmark score of 0, while the percentile rank sits at 50 among all GPUs.
Benchmark Performance
The data for the Mobility Radeon HD 4550 presents a unique challenge: the average benchmark score is 0, and the nearestRivals list is empty. This means no comparative synthetic scores are available, and the percentile rank of 50 is a neutral placement rather than a performance statement. Consequently, the analysis must rely on the raw architectural specifications provided in the fact pack.
The card features 80 shading units, 8 texture mapping units, and 4 render output units. Its compute throughput is rated at 88.00 GFLOPS for FP32 operations, while the pixel fill rate reaches 2.200 GPixel/s and the texture fill rate reaches 4.400 GTexel/s. These are modest figures, indicating a part designed for basic 3D acceleration rather than high-end gaming. The memory subsystem consists of 512 MB of GDDR3 on a 64-bit bus, yielding a bandwidth of 11.20 GB/s. The memory clock is 700 MHz, or 1400 Mbps effective. This bandwidth is a limiting factor; with only 11.20 GB/s, the card cannot feed large textures or high-resolution framebuffers efficiently.
Given the lack of rival data, the numbers speak to an absolute performance envelope. The 2.200 GPixel/s pixel rate suggests that fill-rate-bound scenes will be the primary constraint, while the 4.400 GTexel/s texture rate is similarly low. The FP32 throughput of 88.00 GFLOPS is consistent with a low-end part from the TeraScale era. Without benchmark scores, one can only infer that the card will handle legacy DirectX 10.1 titles at modest settings, but the data does not support any specific frame rate claims. The 64-bit memory bus further limits effective bandwidth, creating a bottleneck that will manifest in any texture-heavy workload. The 4 ROPs cap the pixel throughput, so even if the shading units were underutilized, the card would still be fill-rate limited. The 80 shading units, while numerically present, cannot compensate for the memory and ROP constraints.
Who Should Consider It
The Mobility Radeon HD 4550 is an end-of-life product, and its specifications define a very narrow use case. The 512 MB memory capacity and 11.20 GB/s bandwidth are the primary constraints. For gaming, this means low resolutions and low detail settings are the realistic ceiling. The pixel rate of 2.200 GPixel/s and texture rate of 4.400 GTexel/s will struggle with any modern texture-heavy workload. The card is best suited for portable devices where basic 3D acceleration is needed for older software or lightweight productivity applications, not for contemporary gaming.
The 64-bit memory bus further restricts the effective memory bandwidth, making the card unsuitable for high-resolution framebuffers. With only 4 ROPs, the fill-rate bottleneck is severe. Users with legacy systems that require an MXM-II module might find this card adequate for 2D desktop work or video playback, but the absence of any benchmark scores means no performance guarantees can be made. The data suggests that the card is a placeholder for very light use, and any modern game would likely be unplayable at even minimum settings. The 512 MB framebuffer is a hard limit for texture storage, so games that require more than that will fail to load or suffer from severe swapping. The 11.20 GB/s bandwidth is roughly a tenth of what modern low-end cards offer, but without rival data, no direct comparison is possible. The card's 50th percentile rank, combined with a zero benchmark score, indicates that the database treats it as an average part in terms of placement, but the lack of scores undermines any meaningful percentile interpretation.
Ray Tracing and Feature Set
The feature set is firmly rooted in the DirectX 10.1 era. The card supports DirectX 10.1 with the 10_1 feature level, and OpenGL 3.3. There is no Vulkan support listed, and no ray tracing or tensor cores are present—both fields are null. This means the card lacks any hardware acceleration for ray tracing or AI-based features. The TeraScale architecture does not include dedicated RT or tensor hardware, and the API support confirms this.
For developers and users, this translates to compatibility with older games and applications that target DirectX 10.1 or OpenGL 3.3. No modern features like variable rate shading or mesh shaders are available. The absence of Vulkan further limits the card to legacy software stacks. The display outputs are portable-device dependent, meaning the actual connectors are determined by the laptop or mobile chassis, not the card itself. This is a common trait for MXM modules. The lack of tensor cores also means no DLSS or similar upscaling technology is available, and the absence of RT cores precludes any real-time ray tracing. The card's API support caps at DirectX 10.1, so any title requiring DirectX 11 or 12 will not run. OpenGL 3.3 is similarly dated, limiting compatibility with modern OpenGL applications.
Power and Cooling
The fact pack does not specify a TDP or a suggested PSU, which is typical for a mobile GPU. However, the card lists "None" for power connectors, indicating that it draws all required power from the MXM slot itself. This is a low-power design, though the exact wattage is not provided. The slot width is given as "MXM Module," and the bus interface is MXM-II. This form factor is designed for laptops and portable devices, so cooling is handled by the host system's thermal solution.
Since no power connector is required, installation is straightforward for systems with an MXM-II slot. The absence of a suggested PSU is consistent with a mobile component that does not use an external power supply. The 55 nm process node and 242 million transistors suggest a relatively modest power draw, but without a TDP figure, no specific thermal or power numbers can be stated. The card's end-of-life status means it is no longer in production, but for legacy systems, the lack of auxiliary power connectors simplifies upgrades. The 73 mm² die size is small, which typically correlates with lower power consumption, but again, the exact figure is absent. The transistor density of 3.3 million per square millimeter is a manufacturing metric, not a performance one, and does not influence cooling requirements directly.
