AMD Radeon Pro Vega 16 vs AMD Radeon RX 7800M Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two mobile graphics solutions. In the two shared benchmark tests, the AMD Radeon RX 7800M wins both, and the margins are substantial. The Geekbench OpenCL result places the RX 7800M at 120,778 points against 18,268 points for the Radeon Pro Vega 16, a delta of 561.1%. This is not a marginal improvement; it is a generational leap in raw compute throughput.

The Vulkan result tells a similar story. The RX 7800M scores 126,668 points, while the Pro Vega 16 manages 21,832 points, yielding a 480.2% advantage. Across both head-to-head tests, the RX 7800M claims 2 wins and the Pro Vega 16 records 0 wins. No benchmark in the database shows the Pro Vega 16 ahead.

Context from the nearest rivals reinforces the positioning. The RX 7800M has an average benchmark score of 27,883, which places it just 0.2% ahead of the AMD Radeon Pro Vega 20 (27,839) and 0.3% behind the AMD Radeon Pro W5500X (27,973). It sits 0.5% below the NVIDIA GeForce GTX 980 Ti (28,020) and 0.8% below the AMD FirePro S7150 (28,117). These are tight margins, indicating the RX 7800M competes in a specific performance tier.

The Pro Vega 16, by contrast, has an average score of 23,250. Its nearest rival is the NVIDIA P106-100 at 23,249, a 0% delta. The AMD Radeon RX 6600M (23,273) is 0.1% ahead, and the AMD Radeon R9 M290X (23,276) is also 0.1% ahead. The AMD Radeon AI PRO R9700 (23,315) leads by 0.3%. This cluster suggests the Pro Vega 16 sits at the lower end of a mid-range performance band, far removed from the RX 7800M's position in the 73rd percentile of all GPUs. The Pro Vega 16 lands in the 68th percentile.

Architecture Differences

The architectural divide is stark. The RX 7800M uses the Navi 32 chip built on RDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It belongs to the Navi Mobile (RX 7000M) generation under the codename Wheat Nas. The die contains 28,100 million transistors on a 346 mm² area, yielding a transistor density of 81.2 million per mm². The Pro Vega 16 uses the Vega 12 chip with GCN 5.0 architecture, built on a 14 nm process at GlobalFoundries. No transistor count or die size is recorded for the Vega 12, but the process node alone indicates a significant efficiency gap.

Clock speeds differ substantially. The RX 7800M has a base clock of 1295 MHz, a boost clock of 2335 MHz, and a game clock of 2145 MHz. The Pro Vega 16 operates at a base of 815 MHz and a boost of 1190 MHz. Memory clocks also diverge: the RX 7800M runs at 2250 MHz (18 Gbps effective), while the Pro Vega 16 runs at 1200 MHz (2.4 Gbps effective).

Memory configuration is another major differentiator. The RX 7800M features 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The Pro Vega 16 has 4 GB of HBM2 memory on a 1024-bit bus, delivering 307.2 GB/s. Despite the wider bus, the Pro Vega 16's smaller capacity and lower clock result in less bandwidth.

Compute resources favor the RX 7800M heavily. It has 3840 shading units, 240 texture mapping units, and 96 render output units. It also includes 60 ray tracing cores. The Pro Vega 16 has 1024 shading units, 64 TMUs, and 32 ROPs, with no ray tracing cores. Pixel rate for the RX 7800M is 224.2 GPixel/s versus 38.08 GPixel/s for the Pro Vega 16. Texture rate is 560.4 GTexel/s versus 76.16 GTexel/s.

Peak floating-point performance shows the scale of the gap. The RX 7800M delivers 35.87 TFLOPS FP32 and 35.87 TFLOPS FP16 (1:1 ratio). The Pro Vega 16 delivers 2.437 TFLOPS FP32 and 4.874 TFLOPS FP16 (2:1 ratio). The RX 7800M has roughly 14.7 times the FP32 throughput.

Power and interface also differ. The RX 7800M has a TDP of 180 W and uses PCIe 4.0 x16. The Pro Vega 16 has a TDP of 75 W and uses PCIe 3.0 x16. Both are classified as IGP (integrated graphics processor) in the database, with portable device dependent display outputs. The RX 7800M lists no power connectors, while the Pro Vega 16 lists none as well.

API support favors the newer part. The RX 7800M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Pro Vega 16 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The RX 7800M is marked as Active production, released on September 10, 2024. The Pro Vega 16 is End-of-life, released on November 13, 2018. The RX 7800M's predecessor is listed as Polaris Mobile.

The Verdict

The data points to a clear conclusion: the AMD Radeon RX 7800M is the superior part in every measured dimension. It wins both head-to-head benchmarks by margins exceeding 480%. Its average benchmark score is 4,633 points higher than the Pro Vega 16's average. The RX 7800M sits in the 73rd percentile of all GPUs, while the Pro Vega 16 sits in the 68th percentile.

For workloads that rely on OpenCL or Vulkan, the RX 7800M is the only rational choice. The 561.1% OpenCL delta and the 480.2% Vulkan delta are not close calls. The Pro Vega 16 cannot compete in compute-heavy tasks. Its 2.437 TFLOPS FP32 output is dwarfed by the RX 7800M's 35.87 TFLOPS.

The Pro Vega 16's advantages are limited to power consumption and legacy compatibility. Its 75 W TDP is less than half of the RX 7800M's 180 W. It also supports DirectX 12 (12_1), which is one feature level below the RX 7800M's 12 Ultimate (12_2). For systems constrained by thermal or power budgets, the Pro Vega 16 might be acceptable for basic tasks, but the performance penalty is severe.

The RX 7800M also offers more memory capacity at 12 GB versus 4 GB, higher bandwidth at 432.0 GB/s versus 307.2 GB/s, and support for ray tracing. The Pro Vega 16 has no ray tracing cores. In a modern workload environment, the RX 7800M is the clear winner.

Where Each One Wins

The AMD Radeon RX 7800M wins in compute performance, memory capacity, bandwidth, feature support, and production status. It is the appropriate choice for any application that stresses OpenCL or Vulkan workloads. Its 35.87 TFLOPS FP32 and FP16 performance enables heavy parallel computation. Its 12 GB GDDR6 frame buffer supports larger datasets and higher-resolution textures. The 60 ray tracing cores make it suitable for modern rendering pipelines that use DirectX 12 Ultimate features.

The RX 7800M is also the better option for longevity. It is marked as Active production with a 2024 release date, while the Pro Vega 16 is End-of-life with a 2018 release date. The RX 7800M supports Vulkan 1.4 versus 1.3 on the Pro Vega 16. It also supports DirectX 12 Ultimate versus DirectX 12 (12_1).

The AMD Radeon Pro Vega 16 wins only in power efficiency and legacy compatibility. Its 75 W TDP is 105 W lower than the RX 7800M's 180 W. For systems with strict thermal limits, this could matter. It also uses PCIe 3.0 x16, which may be compatible with older platforms. Its 1024-bit HBM2 bus is wider, but the lower clock and smaller capacity negate any advantage.

For gaming, content creation, or GPU compute, the RX 7800M is the only serious contender. For basic display output on a power-constrained laptop, the Pro Vega 16 might suffice, but benchmark results indicate a massive sacrifice in performance. The data does not support any scenario where the Pro Vega 16 outperforms the RX 7800M in measured tests.
