About AMD Radeon Graphics 448SP
Power and Cooling, TDP, PSU recommendation, connector requirements
The AMD Radeon Graphics 448SP is an integrated graphics processor, not a discrete card, and its power envelope reflects that. The TDP is rated at 45 W, which covers the entire APU package, not just the graphics die. Because this is an IGP, there is no dedicated power connector, the slot width is listed as "IGP," and the power connectors field reads "None." This means the GPU draws all its power through the motherboard's socket power delivery, and no supplementary PCIe power cables are required.
The suggested PSU field is null in the data, which is consistent with an integrated part. For a system builder, the practical implication is that any PSU capable of powering the host CPU and motherboard will suffice; there is no additional headroom needed for a graphics card. The 45 W TDP is notably modest, and benchmark results indicate that thermal management is a motherboard and chassis concern rather than a GPU cooler concern. The chip is fabricated on a 7 nm process at TSMC, with a die size of 180 mm² and a transistor count of 9,800 million, yielding a transistor density of 54.4M per mm². This dense 7 nm design is what allows the entire GPU to operate within that 45 W envelope while still boosting to 1900 MHz.
The base clock is 300 MHz, which is a low idle or light-load state, and the boost clock reaches 1900 MHz under load. The memory is system shared, meaning bandwidth is "System Dependent", there is no dedicated VRAM, and the memory bus width is likewise system shared. This creates a direct dependency on the host system's RAM configuration, which is a key consideration for performance but not for power delivery. The production status is end-of-life, with a release date of April 12, 2021, and the predecessor is Vega IGP while the successor is Navi II IGP.
How It Compares
The nearestRivals field in the data is empty, which means there are no direct comparative scores or deltaPct values provided for this entry. However, the percentileVsAllGpus is 50, placing this GPU exactly at the median of all GPUs in the database. This is a meaningful data point: it indicates that half of all GPUs scored higher and half scored lower, which is a mid-pack position. Without specific rival names or scores, the comparison must be framed in terms of this percentile and the absolute performance figures.
The FP32 performance is 1.702 TFLOPS, the texture rate is 53.20 GTexel/s, and the pixel rate is 15.20 GPixel/s. These are the raw throughput numbers that would place it at the 50th percentile. The FP16 throughput is 3.405 TFLOPS, achieved via a 2:1 ratio, which is typical of GCN architecture. The shading units number 448, with 28 texture mapping units and 8 ROPs. These are the physical resources that deliver the measured rates.
The data shows a clear architectural lineage: GCN 5.1 architecture, codename Cezanne, generation "Vega II IGP (Cezanne)." This is an integrated Vega-based part, not a discrete GPU. Its position in the 50th percentile suggests that while it is not a high-end part, it is also not a low-end outlier. The absence of nearest rivals means the database has not yet computed comparative deltas, but the percentile provides a global anchor.
Ray Tracing and Feature Set
The data explicitly lists rtCores as null and tensorCores as null. This means the AMD Radeon Graphics 448SP has no dedicated ray tracing cores and no tensor cores. Ray tracing, if attempted, would run on the standard shader units, which is a significant limitation for modern workloads that rely on dedicated RT hardware. The architecture is GCN 5.1, which predates AMD's dedicated ray tracing hardware in later generations.
The API support, however, is modern. DirectX 12 (12_1) is supported, which includes the feature level 12_1 feature set. OpenGL 4.6 is supported, and Vulkan 1.3 is supported. These are current API versions that allow the GPU to run modern games and applications, provided those applications do not mandate hardware ray tracing. The DirectX 12_1 feature level includes some advanced rasterization features but does not include DirectX Raytracing (DXR) at the hardware level, since rtCores are absent.
The display outputs are motherboard dependent, which is typical for an IGP. The bus interface is IGP, meaning it communicates over the system bus rather than a PCIe slot. The memory type is system shared, with system shared size and bandwidth. This means the GPU relies on the host system's DDR memory, and the bandwidth is contingent on the memory speed and channel configuration of the host platform.
FAQ
Q: Does the AMD Radeon Graphics 448SP support hardware ray tracing?

Benchmark Performance
The benchmark data for the AMD Radeon Graphics 448SP is sparse, the benchmarks array is empty, and the avgBenchmarkScore is 0. This is likely a data artifact or a placeholder, but the percentileVsAllGpus is 50, which provides a relative performance anchor. A 50th percentile ranking means it sits exactly at the median of all GPUs in the database, outperforming half and trailing half.
The raw compute figures support this mid-range positioning. The FP32 throughput is 1.702 TFLOPS, which is a modest but not negligible number. The texture fill rate is 53.20 GTexel/s, and the pixel fill rate is 15.20 GPixel/s. These numbers are consistent with a 448-shader part clocked at 1900 MHz, given 28 TMUs and 8 ROPs. The FP16 rate of 3.405 TFLOPS at a 2:1 ratio indicates that the hardware can double its throughput for half-precision workloads, which is useful for certain compute tasks but not typically exploited by games.
The nearestRivals field is empty, so no direct percentage deltas can be cited. However, the percentile of 50 is itself a comparative statement. It means that in the database's scoring hierarchy, this GPU is neither a standout nor a laggard. The 7 nm process, with 9,800 million transistors and a die size of 180 mm², is a modern fabrication, but the GCN 5.1 architecture is older. The combination produces a part that is competitive for integrated graphics but cannot match discrete GPUs that occupy higher percentiles.
The memory bandwidth being "System Dependent" is a crucial performance variable. In a dual-channel high-speed DDR4 or DDR5 configuration, the shared memory bandwidth could be substantial, but in a single-channel or slow-memory system, it would bottleneck the GPU. The pixel rate of 15.20 GPixel/s and texture rate of 53.20 GTexel/s are the theoretical maxima, and real-world performance will be lower when memory bandwidth is constrained.
The absence of a suggested PSU and the 45 W TDP indicate that the power delivery is not a performance limiter. The GPU will operate within whatever power budget the host CPU provides. The end-of-life production status and the April 12, 2021 release date place this in a specific era of AMD's IGP lineup, between Vega IGP and Navi II IGP. The data shows a part that is solidly mid-pack, with modern API support but no dedicated ray tracing hardware, and performance that is heavily dependent on the host system's memory configuration.
