AMD Radeon R7 250 vs Intel UHD Graphics P750 Comparison

Head-to-Head Benchmarks

The only recorded benchmark comparison in the database is the Geekbench OpenCL test, and it shows a clear advantage for the AMD Radeon R7 250. The AMD part scores 7,557 points, while the Intel UHD Graphics P750 manages 6,554 points. That is a 15.3% difference in favor of the AMD Radeon R7 250, which is a substantial gap for an integrated graphics solution to try to overcome.

Looking at the percentile rankings, the AMD Radeon R7 250 sits in the 41st percentile of all GPUs, while the Intel UHD Graphics P750 lands in the 38th percentile. The three-percentile gap reinforces the head-to-head result, indicating that the AMD part not only wins this specific test but also holds a higher standing in the broader database distribution.

The nearest rival data for the AMD Radeon R7 250 puts its score in context. It lands within 0.1% of the Intel Arc A310, which scores 7,550 points. It is also just 0.3% behind the AMD Radeon Pro WX 3100 at 7,580 points. Against the NVIDIA GeForce GTX 1650, the R7 250 comes out 1.1% ahead, and it beats the AMD Radeon HD 8850M by 1.5%. These are tight margins, showing that the R7 250 sits in a competitive cluster of older discrete GPUs.

For the Intel UHD Graphics P750, the nearest rivals paint a different picture. It trails the AMD Radeon HD 7730M by 0.4%, with that rival scoring 6,581 points. It sits 0.6% ahead of the NVIDIA GeForce GTX 670M, which scores 6,513 points. The Intel part also falls 0.9% behind the AMD Radeon R7 M460 at 6,612 points, while staying 0.9% ahead of the NVIDIA GeForce GT 555M at 6,493 points. The P750 is essentially locked in a tight battle with mid-range mobile GPUs from several generations ago.

The data shows a single benchmark, but it is decisive. The AMD Radeon R7 250 wins the only recorded head-to-head test, and the delta of 15.3% is meaningful in real-world compute workloads. Users looking at OpenCL performance should expect the R7 250 to deliver noticeably better results than the Intel integrated solution.

Architecture Differences

The two GPUs come from completely different design philosophies. The AMD Radeon R7 250 uses the GCN 1.0 architecture, built on the Cape Verde chip, and belongs to the Volcanic Islands generation within the R7 200 series. It is fabricated on a 28 nm process at TSMC, with 1,500 million transistors packed into a 123 mm² die. The transistor density works out to 12.2 million transistors per square millimeter.

The Intel UHD Graphics P750, by contrast, uses the Generation 12.1 architecture, built on the Rocket Lake chip. It belongs to the HD Graphics-W generation within the Rocket Lake family. Intel fabricates this part on a 14 nm+++ process at its own foundry. The database does not list transistor count, die size, or transistor density for the Intel part, so those figures cannot be compared directly.

The AMD part features 512 shading units, 32 texture mapping units, and 16 raster operation pipelines. The Intel part has 256 shading units, but doubles the texture units to 64 and doubles the raster operation pipelines to 32. This is an interesting split: the AMD GPU has twice the shader count, while the Intel GPU has twice the TMU and ROP counts.

Clock behavior differs significantly. The AMD Radeon R7 250 does not have listed base or boost clocks in the database, but its memory runs at 900 MHz with an effective 1800 Mbps data rate. The Intel UHD Graphics P750 has a base clock of 350 MHz and a boost clock of 1300 MHz, with system-shared memory. The AMD part uses dedicated 1024 MB of DDR3 memory on a 128-bit bus, delivering 28.80 GB/s of bandwidth. The Intel part uses system-shared memory, with bandwidth listed as system dependent.

Pixel and texture rates reflect the architectural differences. The AMD R7 250 outputs 14.80 GPixel/s and 29.60 GTexel/s. The Intel P750 outputs 41.60 GPixel/s and 83.20 GTexel/s, substantially higher in both categories due to its larger ROP and TMU counts. However, the floating-point performance tells a different story: the AMD part delivers 947.2 GFLOPS of FP32 compute, while the Intel part delivers 665.6 GFLOPS. The Intel GPU does have FP16 capability at 1,331.2 GFLOPS with a 2:1 ratio, whereas the AMD part has no listed FP16 performance.

Power consumption is another major differentiator. The AMD Radeon R7 250 has a TDP of 55 W and requires a 250 W power supply. The Intel UHD Graphics P750 has a TDP of just 15 W, which is typical for an integrated GPU. The AMD part is a single-slot card with no power connectors, while the Intel part is an IGP with no separate power requirements. The AMD card measures 168 mm or 6.6 inches in length, while the Intel part has no listed dimensions.

The Verdict

The data points to a straightforward conclusion for compute workloads. The AMD Radeon R7 250 wins the only head-to-head benchmark by 15.3%, and it holds a higher percentile ranking at 41 versus 38. For anyone running OpenCL workloads, the AMD part is the better choice based on the recorded measurements.

The Intel UHD Graphics P750 has clear advantages in other areas, though they do not show up in the single benchmark score. It consumes 40 W less power, offers much higher pixel and texture rates, and includes FP16 support. These features could matter for specific workloads that rely on those capabilities, but the database does not include benchmark results for those scenarios.

The AMD Radeon R7 250 is also a discrete card with its own dedicated memory, which gives it a structural advantage over an IGP that shares system memory. The 1024 MB of DDR3 on a 128-bit bus provides consistent bandwidth, whereas the Intel part depends entirely on the host system's memory configuration.

For buyers choosing between these two, the decision hinges on the use case. The AMD Radeon R7 250 is the stronger performer in the recorded OpenCL test and sits in a higher percentile bracket. The Intel UHD Graphics P750 offers lower power draw and higher throughput in texture and pixel operations, but its overall compute score trails by a meaningful margin. The data shows the AMD part as the winner in raw compute performance, while the Intel part is the more efficient and feature-complete solution for specific tasks.

Specification Differences

The two GPUs differ across nearly every specification category. The process node is a clear split: AMD uses 28 nm from TSMC, while Intel uses 14 nm+++ from its own foundry. The AMD chip contains 1,500 million transistors on a 123 mm² die, with a density of 12.2 million per square millimeter. The Intel chip has no listed transistor or die data.

Memory configurations are fundamentally different. The AMD Radeon R7 250 has 1024 MB of dedicated DDR3 memory on a 128-bit bus, delivering 28.80 GB/s of bandwidth. The Intel UHD Graphics P750 uses system-shared memory, with a system-dependent bus width and bandwidth. The AMD memory clock is 900 MHz with 1800 Mbps effective, while the Intel part has no dedicated memory clock.

Shader and pipeline counts differ substantially. The AMD part has 512 shading units, 32 TMUs, and 16 ROPs. The Intel part has 256 shading units, 64 TMUs, and 32 ROPs. The AMD part leads in FP32 performance at 947.2 GFLOPS, while the Intel part leads in pixel rate at 41.60 GPixel/s and texture rate at 83.20 GTexel/s. The Intel part also has FP16 capability at 1,331.2 GFLOPS, which the AMD part lacks entirely.

Power and physical specifications show the discrete versus integrated divide. The AMD Radeon R7 250 has a 55 W TDP, a single-slot form factor, no power connectors, and a 250 W suggested PSU. The Intel UHD Graphics P750 has a 15 W TDP and is an IGP with no separate power or PSU requirements. The AMD card has a listed length of 168 mm or 6.6 inches, while the Intel part has no dimensions listed.

Interface and display outputs also differ. The AMD part uses PCIe 3.0 x16 and offers 1x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2. The Intel part uses a Ring Bus interface and has motherboard-dependent display outputs. API support shows the Intel part with DirectX 12 (12_1) versus the AMD part's DirectX 12 (11_1), and Vulkan 1.4 versus Vulkan 1.2.170. Both support OpenGL 4.6.
