AMD Radeon Vega 8 Mobile vs Intel UHD Graphics 750 Comparison

Intel UHD Graphics 750 and AMD Radeon Vega 8 Mobile are both end-of-life integrated graphics solutions, but they target different eras and design philosophies. The Intel part, based on Rocket Lake's Generation 12.1 architecture, posts an average benchmark score of 7441, placing it in the 40th percentile of all GPUs. The AMD Radeon Vega 8 Mobile, a GCN 5.0 part from the Raven-M chip, averages 7203, sitting in the 39th percentile. While their average scores are close, the head-to-head benchmark results reveal a clear split: AMD wins the OpenCL test, while Intel dominates Vulkan, indicating that the "better" choice depends entirely on the workload.

Head-to-Head Benchmarks

The two benchmarks provided—Geekbench OpenCL and Geekbench Vulkan—paint opposite pictures of these iGPUs. In the OpenCL test, the AMD Radeon Vega 8 Mobile scores 7435, defeating the Intel UHD Graphics 750's 6743 by a margin of 9.3%. This is a substantial lead for AMD, reflecting its higher shading unit count and raw compute throughput in a general-purpose compute scenario. The Intel part's score of 6743 is closer to older discrete mobile parts; its nearest rivals at this score level include the AMD Radeon HD 8850M (7447, a 0.1% difference) and the NVIDIA GeForce GTX 1650 (7472, a 0.4% difference), though the Intel iGPU trails all of them.

Conversely, the Vulkan test flips the script decisively. The Intel UHD Graphics 750 scores 8138, which is 16.8% higher than the AMD Radeon Vega 8 Mobile's 6970. This is a commanding win for Intel, suggesting its driver stack and architecture handle Vulkan's low-level API overhead more efficiently. The Intel part's Vulkan score is its stronger benchmark; the gap between its Vulkan (8138) and OpenCL (6743) scores is 20.7%, showing a significant API-specific advantage. For AMD, the Vulkan result (6970) is actually lower than its OpenCL score (7435) by 6.3%, indicating the Vega architecture does not scale as well under Vulkan.

Looking at the broader context, the Intel UHD Graphics 750's average score of 7441 places it in close proximity to the AMD Radeon R7 350 (7425, 0.2% ahead) and the NVIDIA GeForce GTX 1650 (7472, 0.4% behind). The AMD Radeon Vega 8 Mobile's average of 7203 puts it near the NVIDIA GeForce GTX 750 (7222, 0.3% behind) and the Intel Iris Pro Graphics P580 (7170, 0.5% ahead). These deltas are all within 1%, meaning that for most real-world tasks, these two iGPUs are effectively performance peers, with the only meaningful differentiation being the API-specific wins.

Where Each One Wins

The AMD Radeon Vega 8 Mobile wins in OpenCL compute workloads. Its 9.3% advantage over the Intel part in that test is driven by its hardware: 512 shading units versus Intel's 256, and 32 texture mapping units versus Intel's 16. This translates to higher theoretical throughput—1,127.4 GFLOPS FP32 versus Intel's 665.6 GFLOPS—which is directly relevant to OpenCL tasks like physics simulations, video encoding filters, and some scientific compute. The Vega 8 Mobile also posts a higher texture rate of 35.23 GTexel/s, more than 1.6 times Intel's 20.80 GTexel/s, which aids in texture-heavy compute workloads.

The Intel UHD Graphics 750 wins in Vulkan-based applications. Its 16.8% lead in the Vulkan benchmark is substantial and suggests that games or applications built on Vulkan will run noticeably smoother on this Intel part. The Intel iGPU also has a higher pixel rate (10.40 GPixel/s versus AMD's 8.808 GPixel/s), which can benefit fill-rate-limited scenarios even though its ROP count is identical (8 for both). Additionally, Intel's support for Vulkan 1.4 (versus AMD's 1.3) may indicate a more modern driver foundation for future Vulkan titles, though the data only shows the current benchmark result.

For general use, the average benchmark scores are nearly identical—7441 for Intel versus 7203 for AMD, a difference of 3.3% in Intel's favor. However, this aggregate hides the API split. If a user's software stack leans on OpenCL, the AMD part is the clear choice; if it leans on Vulkan, the Intel part is superior. Neither card has a universal advantage, as evidenced by the 1-1 split in benchmark wins.

Specification Differences

The core specification differences between these two integrated GPUs are substantial. The Intel UHD Graphics 750 is built on Intel's 14 nm+++ process, while the AMD Radeon Vega 8 Mobile uses a 14 nm node from GlobalFoundries. AMD's chip integrates 4,940 million transistors over a 210 mm² die, giving a density of 23.5M / mm²; Intel does not list transistor or die size data. Clock speeds differ: Intel has a 300 MHz base and 1300 MHz boost, while AMD has a 300 MHz base and a lower 1101 MHz boost. Despite the lower boost clock, AMD compensates with more execution units: 512 shading units and 32 TMUs versus Intel's 256 and 16, respectively. Both have 8 ROPs.

Memory is system-shared for both, with bus width and bandwidth listed as "System Dependent." Pixel rates favor Intel at 10.40 GPixel/s versus AMD's 8.808 GPixel/s, but texture rates favor AMD at 35.23 GTexel/s versus Intel's 20.80 GTexel/s. FP32 compute is higher on AMD (1,127.4 GFLOPS) than Intel (665.6 GFLOPS). The TDP differs significantly: Intel is rated at 15 W, while AMD is rated at 25 W. Display outputs are motherboard dependent for Intel and portable device dependent for AMD. API support is nearly identical, with both supporting DirectX 12 (12_1) and OpenGL 4.6, but Intel supports Vulkan 1.4 while AMD supports Vulkan 1.3.

Architecture Differences

The architectural divide is clear: Intel UHD Graphics 750 uses Generation 12.1 architecture on the Rocket Lake chip, while AMD Radeon Vega 8 Mobile uses GCN 5.0 on the Raven-M chip. Intel's process is 14 nm+++, an improved version of the 14 nm node, whereas AMD's is a standard 14 nm node from GlobalFoundries. The Intel part has no listed transistor or die size, but AMD's 4,940 million transistors indicate a much larger and more complex die (210 mm²). AMD's shading unit count (512) is exactly double Intel's (256), and its TMU count (32) is also double, which explains the texture rate advantage. However, Intel's higher boost clock (1300 MHz versus 1101 MHz) partially offsets AMD's raw unit advantage, particularly in the pixel rate, where Intel leads.

The memory architecture is identical in concept—both use system shared memory with dependent bandwidth—but the underlying memory controller behavior may differ. AMD's predecessor is GCN 3.0 IGP, and its successor is Navi II IGP, showing a clear evolution path. Intel's generation is listed as "HD Graphics (Rocket Lake)," with no predecessor or successor given. Both are end-of-life products, but AMD's release date of 2019-01-07 predates Intel's 2021-03-29 by over two years, meaning the Intel part is newer but built on a similar process node. The TDP difference (15 W for Intel, 25 W for AMD) suggests Intel is more power-efficient per watt, but the data does not provide performance-per-watt metrics to confirm this.

The Verdict

Choose the AMD Radeon Vega 8 Mobile if your primary workload is OpenCL-based compute. The 9.3% lead in that benchmark, combined with double the shading units and TMUs, makes it the stronger choice for tasks that leverage those resources. Its higher FP32 throughput (1,127.4 GFLOPS) and texture rate (35.23 GTexel/s) are concrete advantages in compute-heavy scenarios. This is an older, lower-percentile GPU (39th), but its compute muscle is real.

Choose the Intel UHD Graphics 750 if you are gaming or using applications that favor Vulkan. The 16.8% lead in Vulkan is decisive, and its higher average score (7441) and percentile rank (40th) give it a slight edge in overall performance. The lower TDP (15 W versus 25 W) also makes it a better fit for power-constrained systems, though the data does not quantify the performance impact of that difference. Intel's Vulkan 1.4 support is a forward-looking feature that AMD lacks, potentially future-proofing it for newer titles.

For a neutral recommendation: the Intel UHD Graphics 750 is the safer pick for modern gaming due to its Vulkan performance and newer release date. The AMD Radeon Vega 8 Mobile is the pick for compute tasks that can exploit its parallel architecture. Neither GPU is a clear winner—they split the two benchmarks exactly 1-1—so the decision should be driven by the specific API or application you intend to run most often. If you cannot determine that, the Intel part's higher average score and lower power draw make it the default choice.
