AMD Radeon R7 M350 vs Intel UHD Graphics P750 Comparison

Intel UHD Graphics P750 and AMD Radeon R7 M350 are both end-of-life mobile graphics solutions, but the benchmark data shows a clear, albeit narrow, victory for the AMD part in the single available compute test. The R7 M350 leads the Intel integrated graphics in OpenCL performance by 6.3%, scoring 6991 against 6554. However, the Intel part holds its own in the broader competitive landscape, sitting at the 38th percentile of all GPUs compared to the AMD’s 36th percentile, indicating that raw compute lead does not directly translate to a higher overall standing.

Head-to-Head Benchmarks

The only direct comparison available is the Geekbench OpenCL test, which measures general-purpose compute performance. In this test, the AMD Radeon R7 M350 scores 6991, while the Intel UHD Graphics P750 scores 6554. This results in a delta of -6.3% for the Intel part, meaning the AMD GPU is 6.3% faster in this specific workload. This is a modest but definitive win for the discrete AMD solution, which leverages its higher shading unit count and dedicated memory to pull ahead in raw parallel processing.

Despite losing the head-to-head, the Intel UHD Graphics P750’s average score of 6554 places it near a cluster of older discrete mobile GPUs. It is effectively tied with the AMD Radeon HD 7730M, which scores 6581 (a -0.4% delta for the Intel part), and it slightly edges out the NVIDIA GeForce GTX 670M, which scores 6513 (a +0.6% delta). The Intel chip also trails the AMD Radeon R7 M460 by just 0.9% (6612) and leads the NVIDIA GeForce GT 555M by 0.9% (6493). These tight margins suggest that the P750’s compute performance is firmly in the range of mid-tier discrete GPUs from several generations ago, despite being an integrated solution.

The AMD Radeon R7 M350’s average benchmark score is 6327, which is lower than its OpenCL score due to the inclusion of a Vulkan test where it scores 5662. This average places it in direct competition with the AMD Radeon Pro WX 4100 (6330, 0% delta) and ahead of the NVIDIA Quadro K620 (6282, +0.7%) and the high-end NVIDIA GeForce RTX 5070 Ti SUPER (6270, +0.9%). The fact that the R7 M350’s average is dragged down by its Vulkan score, while its OpenCL score is higher, indicates that its performance is highly API-dependent, a characteristic of its GCN 3.0 architecture.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The Intel UHD Graphics P750 is based on Intel’s Generation 12.1 architecture, fabricated on a 14 nm+++ process at Intel’s own foundries. It is part of the Rocket Lake platform and features 256 shading units, 64 texture mapping units (TMUs), and 32 raster operation units (ROPs). It operates at a base clock of 350 MHz with a boost clock of 1300 MHz. The AMD Radeon R7 M350, in contrast, uses the older GCN 3.0 architecture on a 28 nm process at TSMC. It has a higher transistor count of 1,550 million on a 125 mm² die, yielding a transistor density of 12.4M per mm², and packs 384 shading units, 24 TMUs, and only 8 ROPs. Its clocks are much higher, with a base of 1000 MHz and a boost of 1015 MHz.

Memory is another major differentiator. The Intel P750 uses system-shared memory, meaning its bandwidth is system-dependent and its memory size is shared with the CPU. The AMD R7 M350 has 4 GB of dedicated DDR3 memory on a 64-bit bus, delivering 16.00 GB/s of bandwidth. This dedicated memory gives the AMD part a significant advantage in memory-intensive tasks, as it does not compete with the CPU for bandwidth. The Intel part’s memory clock is listed as "System Shared" and its bandwidth as "System Dependent," highlighting its reliance on the host system’s RAM configuration.

The compute capabilities also differ in their FP32 and FP16 throughput. The Intel P750 delivers 665.6 GFLOPS of FP32 performance and 1,331.2 GFLOPS of FP16 using a 2:1 ratio, indicating it can double its throughput on half-precision workloads. The AMD R7 M350 provides 779.5 GFLOPS of FP32 and the same 779.5 GFLOPS of FP16, using a 1:1 ratio, meaning it does not accelerate half-precision tasks. This gives the Intel part a theoretical advantage in FP16-heavy workloads, despite its lower FP32 output. Pixel and texture rates follow the same trend: the Intel part has a pixel rate of 41.60 GPixel/s and a texture rate of 83.20 GTexel/s, while the AMD part trails significantly at 8.120 GPixel/s and 24.36 GTexel/s, respectively.

Where Each One Wins

The AMD Radeon R7 M350 wins in raw compute throughput, as evidenced by its 6.3% lead in the OpenCL benchmark. This is likely due to its higher shading unit count (384 vs 256) and dedicated memory bandwidth, which allows it to feed those units more effectively. The R7 M350 also has a higher FP32 output (779.5 GFLOPS vs 665.6 GFLOPS), making it the better choice for general-purpose compute tasks that are not heavily dependent on half-precision math. Its dedicated 4 GB of VRAM also makes it more suitable for workloads that require a stable, isolated memory pool, such as larger texture sets or datasets that cannot fit in shared system memory.

The Intel UHD Graphics P750 wins in specific architectural features. Its pixel rate of 41.60 GPixel/s is over five times higher than the AMD part’s 8.120 GPixel/s, and its texture rate of 83.20 GTexel/s is more than three times higher. This suggests that the Intel part is better optimized for fill-rate-bound graphics workloads, such as traditional rasterization tasks at lower resolutions. The Intel part also has a significant advantage in FP16 compute, delivering 1,331.2 GFLOPS versus the AMD’s 779.5 GFLOPS. This is critical for applications that leverage half-precision for AI inference or image processing, where the Intel part can effectively double its throughput. The Intel part also supports a newer Vulkan version (1.4 vs 1.2.170) and DirectX 12_1, while the AMD part only supports DirectX 12_0, indicating better modern API feature support on the Intel side.

In terms of competitive positioning, the Intel P750’s 38th percentile ranking is slightly higher than the R7 M350’s 36th percentile, despite the AMD part winning the direct benchmark. This suggests that the Intel part’s overall performance profile, when averaged across various workloads and driver optimizations, is slightly more consistent or better aligned with the broader GPU ecosystem. The AMD part’s average score of 6327 is pulled down by its Vulkan score of 5662, which is significantly lower than its OpenCL score, indicating a potential weakness in Vulkan-specific applications.

The Verdict

From the data, the AMD Radeon R7 M350 is the better choice for pure compute performance, as it wins the only head-to-head benchmark and offers higher FP32 throughput and dedicated memory. Users who need a discrete GPU for OpenCL-based workloads, such as video encoding, scientific simulation, or data processing, will find the R7 M350 to be 6.3% faster than the Intel integrated solution. Its dedicated 4 GB DDR3 memory also provides a more predictable and isolated memory environment, which is preferable for tasks that require consistent memory bandwidth without system contention.

However, the Intel UHD Graphics P750 is the better choice for modern API support and specific graphics workloads. Its support for DirectX 12_1 and Vulkan 1.4, compared to the AMD’s DirectX 12_0 and Vulkan 1.2.170, makes it more future-proof for software that leverages these newer features. Its massively higher pixel and texture rates (41.60 GPixel/s and 83.20 GTexel/s vs 8.120 GPixel/s and 24.36 GTexel/s) make it superior for fill-rate-bound scenarios, which are common in older games or 2D applications. The Intel part also has a decisive advantage in FP16 compute, making it the better option for AI-heavy workloads that use half-precision inference.

The choice ultimately depends on the primary use case. If the user’s priority is maximum raw compute in OpenCL or stable dedicated memory, the AMD Radeon R7 M350 is the winner. If the user requires modern API features, high fill rates, or accelerated FP16 math, the Intel UHD Graphics P750 is the superior product. The data does not support a universal winner, as each GPU leads in different metrics that matter to different applications.
