AMD Radeon Pro VII vs NVIDIA RTX A4500 Mobile Comparison

NVIDIA RTX A4500 Mobile and AMD Radeon Pro VII are both professional-grade GPUs that land in the 95th percentile of all GPUs, yet they are built on fundamentally different philosophies. The former is a mobile Ampere part with modern features, while the latter is a desktop Vega 20 card with a colossal memory bus. Their average benchmark scores sit close — 91,134 for the NVIDIA and 88,961 for the AMD — but the individual tests reveal a stark split in workload preferences. This analysis breaks down their specifications, architecture, and real benchmark data to determine where each card stands.

Specification Differences

The two cards diverge significantly in their core specifications. The NVIDIA RTX A4500 Mobile packs 5,888 shading units, 184 TMUs, and 96 ROPs, whereas the AMD Radeon Pro VII has 3,840 shading units, 240 TMUs, and 64 ROPs. This means NVIDIA has far more shader cores but fewer texture units.

Clock speeds also differ: the NVIDIA runs at a base of 930 MHz and boosts to 1500 MHz, while the AMD starts at 1400 MHz and boosts to 1700 MHz. The AMD's higher clocks help it achieve a texture rate of 408.0 GTexel/s, which outpaces the NVIDIA's 276.0 GTexel/s. However, the NVIDIA counters with a pixel rate of 144.0 GPixel/s versus the AMD's 108.8 GPixel/s.

Memory bandwidth is where the AMD dominates. Its HBM2 memory on a 4096-bit bus delivers 1.02 TB/s, exactly double the 512.0 GB/s from the NVIDIA's GDDR6 on a 256-bit bus. Memory clock speeds are listed as 2000 MHz (16 Gbps effective) for the NVIDIA and 1000 MHz (2 Gbps effective) for the AMD.

Physical requirements differ as well. The AMD is a dual-slot card measuring 305 mm in length, requiring 1x 6-pin and 1x 8-pin power connectors and a 600 W suggested PSU. The NVIDIA is a mobile part with no power connectors listed and a 140 W TDP. The AMD outputs via 6x mini-DisplayPort 1.4a, while the NVIDIA's display outputs are listed as portable device dependent.

Architecture Differences

The NVIDIA RTX A4500 Mobile uses the GA104 chip based on Ampere architecture, fabricated on Samsung's 8 nm process. It contains 17,400 million transistors on a 392 mm² die, yielding a transistor density of 44.4M per mm². This is a modern architecture that includes 46 ray tracing cores and 184 tensor cores, making it capable of hardware-accelerated ray tracing and AI workloads. Its API support includes DirectX 12 Ultimate (12_2) and Vulkan 1.4.

The AMD Radeon Pro VII uses the Vega 20 chip based on GCN 5.1 architecture, built on TSMC's 7 nm process. It has 13,230 million transistors on a 331 mm² die, with a slightly lower density of 40.0M per mm². This architecture lacks dedicated ray tracing and tensor cores, as evidenced by its null entries for those fields. Its API support stops at DirectX 12 (12_1) and Vulkan 1.3.

FP32 compute favors the NVIDIA at 17.66 TFLOPS versus the AMD's 13.06 TFLOPS. However, the AMD flips the script on FP16: it delivers 26.11 TFLOPS with a 2:1 ratio, while the NVIDIA matches its FP32 rate at 17.66 TFLOPS with a 1:1 ratio. The AMD's 7 nm node and HBM2 memory are its architectural highlights, while the NVIDIA counters with raw shader count and dedicated acceleration blocks.

The Verdict

The data points to a clear split: the NVIDIA RTX A4500 Mobile is the compute king, while the AMD Radeon Pro VII is the graphics API specialist. For users who rely on OpenCL-heavy workloads — such as general compute, simulation, or rendering — the NVIDIA's 16.8% lead in that test is decisive. Its 46 ray tracing cores and 184 tensor cores also future-proof it for applications that leverage those features.

The AMD Radeon Pro VII wins the Vulkan test by 12.3%, which suggests better performance in Vulkan-based games or compute applications. Its 1.02 TB/s memory bandwidth is a massive advantage for memory-bound tasks, and its higher texture rate (408.0 GTexel/s) helps in scenarios that hammer texture units. That said, its 250 W TDP and dual-slot, 305 mm length make it a desktop-only proposition.

Choose the NVIDIA for mobile workstations, modern feature support, and higher raw FP32 compute. Choose the AMD for desktop setups where power is less of a concern and where Vulkan performance or massive memory bandwidth outweighs everything else. Neither card is a universal winner; the benchmark results show one win each, with margin differences of 16.8% and 12.3% respectively.

Head-to-Head Benchmarks

The Geekbench OpenCL test is a landslide for the NVIDIA RTX A4500 Mobile. It scores 105,307 against the AMD's 90,148, a 16.8% delta. This result aligns with the NVIDIA's higher FP32 throughput (17.66 TFLOPS vs 13.06 TFLOPS) and greater shader count. In the nearest rival comparison, the NVIDIA's avg score of 91,134 places it 2.4% above the AMD's 88,961, and it sits just 0.6% behind the AMD Radeon RX 7900M (91,713).

The Geekbench Vulkan test tells the opposite story. The AMD Radeon Pro VII wins with 87,774 points, beating the NVIDIA's 76,960 by 12.3%. This is notable because the NVIDIA has a newer architecture with Vulkan 1.4 support, yet the AMD's older GCN design outperforms it in this API. The AMD's advantage here may stem from its superior memory bandwidth, which helps feed data to the GPU faster in API-specific workloads.

Looking at the broader rival landscape, the AMD Radeon Pro VII's avg score of 88,961 places it 0.5% ahead of the NVIDIA Quadro GP100 (88,528) and 3.6% ahead of the AMD Radeon PRO W7600 (85,851). The NVIDIA RTX A4500 Mobile, by contrast, is 2.9% ahead of the Quadro GP100 and 1.1% behind the desktop NVIDIA RTX A4500 (92,145). These deltas show both cards are competitive within their respective peer groups.

Where Each One Wins

The NVIDIA RTX A4500 Mobile wins in OpenCL compute scenarios. Its 105,307 OpenCL score is the highest single benchmark result between the two, and it pairs that with a 140 W TDP — 110 W lower than the AMD's 250 W. This makes it the clear choice for mobile workstations or any environment where power efficiency matters. The inclusion of 46 ray tracing cores and 184 tensor cores means it can handle emerging workloads that the AMD simply cannot process with dedicated hardware. Its 16 GB GDDR6 memory is equal in capacity, though lower in bandwidth, so it suits tasks that are shader-bound rather than memory-bandwidth-bound.

The AMD Radeon Pro VII wins in Vulkan-based applications and memory-heavy workloads. Its 87,774 Vulkan score demonstrates a 12.3% advantage that cannot be ignored, particularly for users running Vulkan compute or modern game engines. The 1.02 TB/s memory bandwidth is the standout specification here — it is exactly double the NVIDIA's bandwidth, which can be decisive in large dataset processing, high-resolution textures, or any operation that saturates the memory bus. Its 408.0 GTexel/s texture rate also exceeds the NVIDIA's 276.0 GTexel/s, giving it an edge in texturing throughput. The trade-off is its 250 W TDP, dual-slot size, and 305 mm length, which restrict it to spacious desktop chassis with robust power supplies.

In summary, the NVIDIA is the better all-around compute device with modern features and lower power draw, while the AMD is a specialized tool for Vulkan and bandwidth-hungry tasks. Benchmark results show a 1-1 split, so the decision hinges on which API and workload profile matches your needs.
