AMD Radeon Vega 10 Mobile vs Intel Iris Pro Graphics P6300 Comparison

AMD Radeon Vega 10 Mobile and Intel Iris Pro Graphics P6300 are both integrated graphics solutions from their respective manufacturers, aimed at different eras of mobile computing. The data in the database places them in adjacent performance tiers, with the AMD part holding a clear edge in the single recorded benchmark. The AMD Radeon Vega 10 Mobile, built on the Raven-M chip with GCN 5.0 architecture, represents a much newer design than the Intel Iris Pro Graphics P6300, which uses the Broadwell GT3e die from Intel's Generation 8.0 architecture. Both are end-of-life products now, but their benchmark results still illustrate how integrated graphics evolved over half a decade.

Head-to-Head Benchmarks

The only head-to-head benchmark recorded in the database is Geekbench OpenCL. In this test, the AMD Radeon Vega 10 Mobile scores 6476 points, while the Intel Iris Pro Graphics P6300 scores 5712 points. The delta percentage is 13.4 percent in favor of the AMD part. This is a substantial margin for integrated graphics, indicating that the Vega 10 Mobile delivers noticeably higher compute throughput in OpenCL workloads.

To put that score into perspective, the AMD Radeon Vega 10 Mobile sits at the 37th percentile of all GPUs in the database. Its nearest rivals are clustered tightly around its score. The NVIDIA Quadro M5000M averages 6481 points, which is only 0.1 percent higher than the Vega 10 Mobile. The NVIDIA GeForce GT 555M scores 6493, a 0.3 percent advantage. The NVIDIA GeForce GTX 670M averages 6513, which is 0.6 percent ahead. On the other side, the NVIDIA RTX PRO 5000 72 GB Blackwell scores 6407, putting it 1.1 percent behind the AMD part. This tight grouping shows that the Vega 10 Mobile sits in a competitive band, trading blows with discrete mobile GPUs from several generations.

The Intel Iris Pro Graphics P6300 sits at the 33rd percentile of all GPUs. Its nearest rivals also form a close cluster. The NVIDIA GeForce GTX 670MX averages 5721 points, just 0.1 percent above the Intel part. The NVIDIA GeForce GTX 550 Ti scores 5731, a 0.3 percent lead. Behind it, the AMD Radeon HD 8790M averages 5691 points, which is 0.4 percent below the Iris Pro P6300. The NVIDIA Quadro M500M scores 5604, putting it 1.9 percent behind. Like the AMD part, the Intel solution sits near a group of older discrete GPUs, but at a lower performance level overall.

The 13.4 percent delta between the two integrated parts is larger than the gaps between either GPU and its immediate rivals. This suggests that the architectural and generational differences between the Vega 10 Mobile and the Iris Pro P6300 are more significant than the differences between these parts and their respective discrete competitors. In practical terms, the AMD part delivers a clear win in OpenCL compute performance, which is the only metric the database records for both.

The Verdict

Based on the recorded data, the AMD Radeon Vega 10 Mobile is the faster GPU. It wins the only head-to-head benchmark, and it does so by a meaningful 13.4 percent margin. Its score of 6476 exceeds the Intel Iris Pro Graphics P6300's 5712 by 764 points. The AMD part also holds a higher percentile ranking, sitting at 37 percent of all GPUs compared to Intel's 33 percent.

Who should pick which? The data supports the AMD Radeon Vega 10 Mobile for anyone prioritizing raw OpenCL compute performance in a mobile integrated GPU. Its higher shading unit count, higher boost clock, and newer architecture all contribute to its advantage. The Intel Iris Pro Graphics P6300 is not without merit, but in the measured benchmark, it trails clearly. It does have a higher texture mapping unit count and a lower thermal design power, but those do not translate into a benchmark win.

If the workload is heavily dependent on OpenCL acceleration, the AMD part is the obvious choice from this data. The Intel part may still be serviceable for lighter duties, but the benchmark results show it is a step behind. The database records only one benchmark, so the verdict is necessarily narrow, but within that scope, AMD wins decisively.

Where Each One Wins

The AMD Radeon Vega 10 Mobile wins in raw compute performance. Its Geekbench OpenCL score of 6476 is higher, and its FP32 throughput is listed at 1.665 TFLOPS compared to the Intel part's 614.4 GFLOPS. The AMD part also has a much higher boost clock at 1301 MHz versus 800 MHz for the Intel part. The shading unit count favors AMD as well, with 640 shading units against Intel's 384. The AMD part also supports newer API versions, including DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3, while the Intel part supports DirectX 12 (11_1), OpenGL 4.4, and Vulkan 1.0. For modern applications that leverage these newer APIs, the AMD part is better positioned.

The Intel Iris Pro Graphics P6300 does have some advantages in specific specifications. It has 48 texture mapping units, compared to 40 on the AMD part. Its texture rate is 38.40 GTexel/s, while the AMD part achieves 52.04 GTexel/s. The Intel part also has a lower thermal design power at 15 W, which is actually higher than the AMD part's 10 W, so that is not an advantage. The Intel part's pixel rate is 4.800 GPixel/s, which is lower than the AMD part's 10.41 GPixel/s. The Intel part does have a different bus interface, listed as Ring Bus, while the AMD part uses IGP. This is a technical distinction that does not show up in benchmark results.

The AMD part wins in every performance metric recorded in the database. Its pixel rate is more than double that of the Intel part. Its texture rate is higher despite having fewer texture mapping units, which reflects its higher clock speed. Its FP32 throughput is nearly three times higher. The only category where the Intel part exceeds the AMD part is texture mapping unit count, but that does not translate into a performance win in the recorded benchmark.

Architecture Differences

The AMD Radeon Vega 10 Mobile is built on the Raven-M chip using GCN 5.0 architecture. This is a Vega IGP from the Raven Ridge-M generation. It is fabricated on a 14 nm process at GlobalFoundries. The chip contains 4,940 million transistors on a die size of 210 mm², resulting in a transistor density of 23.5 million transistors per square millimeter. The architecture supports FP16 computation at a 2:1 ratio, with FP16 throughput listed at 3.331 TFLOPS and FP32 at 1.665 TFLOPS. The AMD part has 640 shading units, 40 texture mapping units, and 8 render output units. Its pixel rate is 10.41 GPixel/s and its texture rate is 52.04 GTexel/s. The predecessor is listed as GCN 3.0 IGP, and the successor is Navi II IGP.

The Intel Iris Pro Graphics P6300 is built on the Broadwell GT3e chip using Generation 8.0 architecture. This is an HD Graphics-W part from the Broadwell generation. It is also fabricated on a 14 nm process, but at Intel's foundry. The database does not list transistor count, die size, or transistor density for this part. The architecture does not list FP16 support. The Intel part has 384 shading units, 48 texture mapping units, and 6 render output units. Its pixel rate is 4.800 GPixel/s and its texture rate is 38.40 GTexel/s. No predecessor or successor is listed in the database.

The architectural divide is clear: AMD uses a newer GCN 5.0 design with higher clock speeds and more shading units, while Intel uses an older Generation 8.0 design with more texture mapping units but lower clocks. The AMD part also has a higher transistor count and larger die, reflecting its more complex compute capabilities. The FP16 support on the AMD part is a notable feature that the Intel part lacks entirely.
