AMD Radeon 8065S vs NVIDIA RTX PRO 4500 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon 8065S contains no benchmark scores, while the NVIDIA RTX PRO 4500 Blackwell has a full set of nine benchmark results. This makes the head-to-head comparison one-sided in terms of measured performance. The RTX PRO 4500 Blackwell posts an average benchmark score of 31532, placing it in the 76th percentile of all GPUs in the database. The Radeon 8065S sits at the 50th percentile with an average benchmark score of zero, reflecting the absence of recorded benchmark data rather than a lack of capability.

The RTX PRO 4500 Blackwell delivers its strongest result in the Geekbench Vulkan test with a score of 221768. In Passmark's DirectX 9 test it scores 397, which is its highest Passmark API result. The DirectX 11 test yields 320, while the DirectX 10 test produces 204. The DirectX 12 result is the lowest API score at 119. The Passmark G3D score reaches 33360, and the GPU compute score is 19255. The 2D graphics test returns 1336. In the 3DMark Steel Nomad DX12 test, the card scores 7025.

The nearest rivals in the database provide context for the RTX PRO 4500 Blackwell's recorded performance. The NVIDIA TITAN RTX averages 31676, which is 0.5 percent higher than the RTX PRO 4500 Blackwell's average. The NVIDIA GRID M60-1Q averages 31220, placing it 1 percent below. The NVIDIA Quadro M5000 also averages 31220, also 1 percent below. The Intel Arc Pro A30M averages 31894, which is 1.1 percent above the RTX PRO 4500 Blackwell. The RTX PRO 4500 Blackwell therefore sits in a tight cluster with these four cards, separated by no more than 1.1 percent in either direction. Its 76th percentile ranking reflects this competitive positioning.

Because the Radeon 8065S has no benchmark entries, the database shows zero wins for it in head-to-head comparisons. The RTX PRO 4500 Blackwell also shows zero wins, as the head-to-head benchmark list is empty. The comparative analysis must therefore rely on architectural and specification differences rather than direct measured scores.

The Verdict

The data indicates a clear division of roles. The NVIDIA RTX PRO 4500 Blackwell is the only one of the two with recorded benchmark results, and those results place it in the 76th percentile of all GPUs. Its average score of 31532 puts it within 1.1 percent of four nearby rivals, confirming it operates in a well-established performance tier. The card carries 32 GB of GDDR7 memory on a 256-bit bus with 896.0 GB/s of bandwidth, which suits large data sets and professional workloads.

The AMD Radeon 8065S uses system shared memory with bandwidth described as system dependent. It has no dedicated VRAM capacity listed. This design targets a different usage pattern, one where the GPU pulls from the host system's memory pool rather than maintaining its own pool. The 55 W thermal design power and integrated graphics package (IGP) slot width reinforce this positioning as a low-power, mobile-oriented part.

For users who need a discrete, dual-slot, 200 W card with its own 32 GB GDDR7 frame buffer, the RTX PRO 4500 Blackwell is the only choice supported by measured data. For users who need an integrated graphics solution within a 55 W envelope, the Radeon 8065S fits that profile. The database does not provide benchmark scores for the Radeon 8065S, so no performance claim can be made for it.

Where Each One Wins

The NVIDIA RTX PRO 4500 Blackwell wins in every measured category because it is the only card with recorded benchmark data. Its 76th percentile ranking and average score of 31532 confirm it operates in a competitive tier alongside the TITAN RTX, GRID M60-1Q, Quadro M5000, and Arc Pro A30M. The 32 GB GDDR7 frame buffer with 896.0 GB/s of bandwidth and 50.53 TFLOPS of FP32 compute make it suited for rendering, compute, and AI workloads that benefit from tensor cores. Its four DisplayPort 2.1b outputs support multi-display professional setups. The 200 W TDP and dual-slot design indicate a desktop workstation card that expects a dedicated power feed.

The AMD Radeon 8065S wins in power efficiency and integration. Its 55 W TDP is far below the NVIDIA card's 200 W, and its IGP slot width with no power connectors means it does not require a discrete power cable. The system shared memory design removes the need for a dedicated VRAM pool, which can simplify system configuration in portable devices. The 3000 MHz boost clock is higher than the RTX PRO 4500 Blackwell's 2407 MHz boost clock, and the 4 nm process node is smaller than the 5 nm node used by NVIDIA. The Radeon 8065S also carries the Navi Mobile (RX 8000M) generation label, confirming its mobile-oriented positioning, while the RTX PRO 4500 Blackwell belongs to the Blackwell PRO W (x000) workstation generation.

For a builder selecting between the two, the choice rests on form factor and workload. A discrete workstation card with dedicated memory and measured performance points to the RTX PRO 4500 Blackwell. A low-power integrated solution for a portable device points to the Radeon 8065S. The database does not contain benchmark results for the Radeon 8065S, so any performance comparison beyond specifications is not supported by the recorded data.
