AMD Radeon RX 6650M vs NVIDIA RTX A5500 Comparison

The database records a clear mismatch between these two parts: a workstation-class desktop card facing a mobile gaming GPU. The NVIDIA RTX A5500 and AMD Radeon RX 6650M were both released in 2022 and both carry end-of-life status, but they occupy entirely different tiers of the performance landscape. The A5500 sits in the 97th percentile of all GPUs measured, while the RX 6650M sits at the 91st percentile. That gap of several percentile points translates into benchmark deltas that exceed a factor of two. Every recorded head-to-head test favors the A5500, and the analysis below walks through exactly how large those margins are.

Head-to-Head Benchmarks

The recorded data contains two direct comparison tests, and the RTX A5500 wins both decisively.

In Geekbench OpenCL, the A5500 scores 174637 against 65800 for the RX 6650M, a delta of 165.4 percent in the workstation card's favor. That is not a close contest: the A5500 delivers well over twice the throughput of the mobile Radeon part on this compute workload. The OpenCL result is the largest gap in the dataset, which is consistent with the A5500's professional orientation, where general-purpose compute throughput is a primary design target.

Geekbench Vulkan tells a similar story with a smaller margin. The A5500 posts 155797 while the RX 6650M records 77735, a delta of 100.4 percent. Even on the graphics-focused API where the RDNA 2.0 architecture is generally at its strongest relative to rivals, the RX 6650M still trails by a factor of just over two. The database shows the RX 6650M actually performing better in Vulkan than in OpenCL relative to its rival, closing roughly two thirds of nothing in absolute terms but improving its relative standing from a 165.4 percent deficit to a 100.4 percent one.

The aggregate numbers confirm the per-test picture. The A5500's average benchmark score is 165217, compared with 71768 for the RX 6650M. The head-to-head tally stands at two wins for the A5500 and zero for the RX 6650M. There is no recorded workload in which the mobile AMD part comes out ahead.

Context from each card's rival set sharpens the contrast. The A5500 trades blows with the AMD Radeon PRO W7800 (average score 164894, a delta of 0.2 percent), the NVIDIA RTX 4500 Ada Generation (166094, a delta of -0.5 percent), the NVIDIA A100 PCIe 40 GB (162504, a delta of 1.7 percent), and the AMD Radeon Pro W6900X (168574, a delta of -2 percent). The RX 6650M's neighborhood is entirely different: the NVIDIA TITAN X Pascal (72098, a delta of -0.5 percent), the AMD Radeon Pro Vega 64 (72379, a delta of -0.8 percent), the AMD Radeon RX 6600 LE (70829, a delta of 1.3 percent), and the AMD Radeon Vega Frontier Edition (73370, a delta of -2.2 percent). The A5500's closest rivals sit at more than double the average scores of the RX 6650M's closest rivals.

The Verdict

The data supports a simple recommendation. Anyone whose workload demands maximum throughput should pick the RTX A5500: it wins every recorded benchmark, by margins of 100.4 percent or more, and it brings 24 GB of memory and 320 tensor cores to tasks that the RX 6650M, with 8 GB and no dedicated tensor hardware, cannot match in capability.

The RX 6650M's case rests on platform characteristics rather than raw scores. It is a 120 W mobile part with no power connectors, integrated into the host platform as an IGP-class component, whereas the A5500 is a 230 W dual-slot card requiring a single 8-pin connector and a suggested 550 W system power supply. Where the deployment target is a portable device with portable-device-dependent display outputs, the RX 6650M is the only one of the two that fits the form factor at all. Neither part is a current-production option, as both carry end-of-life status in the database.

Architecture Differences

The two GPUs diverge at nearly every architectural layer. The A5500 is built on the GA102 chip, part of NVIDIA's Ampere architecture and the Workstation Ampere (Ax000) generation. It is fabricated on an 8 nm process at Samsung, packing 28,300 million transistors onto a 628 mm² die, for a density of 45.1M transistors per mm². Its lineage runs from the Quadro Turing predecessor toward the Workstation Ada successor.

The RX 6650M uses the Navi 23 chip, part of AMD's RDNA 2.0 architecture and the Navi Mobile (RX 6000M) generation. It is fabricated on a 7 nm process at TSMC, with 11,060 million transistors on a 237 mm² die and a slightly higher density of 46.7M transistors per mm². Its predecessor line is Polaris Mobile.

The die-size difference alone tells much of the story: 628 mm² versus 237 mm². The A5500's silicon budget buys 10240 shading units, 320 TMUs, 96 ROPs, 80 RT cores, and 320 tensor cores. The RX 6650M fields 1792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores, with no tensor cores listed. Clock strategies run opposite to the resource counts: the A5500 runs at a 1080 MHz base and 1665 MHz boost, while the RX 6650M runs considerably higher at a 2068 MHz base, 2222 MHz game clock, and 2416 MHz boost. The higher clocks partially offset the smaller resource counts in pixel throughput: the pixel rates are nearly identical at 159.8 GPixel/s for the A5500 and 154.6 GPixel/s for the RX 6650M. Texture rates diverge sharply, at 532.8 GTexel/s versus 270.6 GTexel/s.

Compute throughput reflects the shading-unit gap. The A5500 delivers 34.10 TFLOPS of FP32, against 8.659 TFLOPS for the RX 6650M. In FP16 the A5500 runs at a 1:1 ratio for 34.10 TFLOPS, while the RX 6650M's 2:1 rate yields 17.32 TFLOPS.

Specification Differences

The memory subsystems are the starkest contrast in the spec sheet. The A5500 carries 24 GB of GDDR6 on a 384-bit bus running at 2000 MHz (16 Gbps effective), delivering 768.0 GB/s of bandwidth. The RX 6650M has 8 GB of GDDR6 on a 128-bit bus at 1750 MHz (14 Gbps effective), delivering 224.0 GB/s. That is three times the capacity and well over three times the bandwidth.

Bus interfaces differ: PCIe 4.0 x16 for the A5500, PCIe 4.0 x8 for the RX 6650M. Display outputs are fixed at 4x DisplayPort 1.4a on the A5500, while the RX 6650M's outputs are listed as portable device dependent. The A5500 has recorded dimensions of 267 mm (10.5 inches) in length and 112 mm (4.4 inches) in height; the RX 6650M has no recorded dimensions. Release dates are close: 2022-03-21 for the A5500 and 2022-01-03 for the RX 6650M. API support is identical on paper, with both supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The RTX A5500 wins everywhere the benchmark data measures. It dominates compute-oriented OpenCL work by 165.4 percent and graphics-oriented Vulkan work by 100.4 percent. Its 24 GB of memory, 768.0 GB/s of bandwidth, 320 tensor cores, and full x16 PCIe 4.0 link make it the recorded-data choice for demanding professional and compute workloads. Its FP32 throughput of 34.10 TFLOPS dwarfs the RX 6650M's 8.659 TFLOPS.

The RX 6650M wins where the A5500 simply cannot participate: portable deployments. Its 120 W TDP, absence of power connectors, IGP integration, and portable-device-dependent display outputs define a use case the dual-slot, 267 mm-long workstation card cannot serve. Within its own tier, it performs respectably, sitting within 2.2 percent of rivals like the TITAN X Pascal and Radeon Pro Vega 64. The pixel-rate parity is also notable: at 154.6 GPixel/s it nearly matches the A5500's 159.8 GPixel/s, suggesting that in pure fill-rate-bound scenarios the raw gap is narrower than the compute numbers imply. For everything else the database measures, the A5500 is the stronger part by a factor of two or more.
