AMD Radeon RX 5600 OEM vs AMD Radeon RX 6650M XT Comparison

Where Each One Wins

The benchmark data splits cleanly between these two AMD parts, though the split is heavily one-sided. The AMD Radeon RX 6650M XT takes the only head-to-head victory recorded in the database, winning the Geekbench OpenCL test with a score of 76,904 against 62,427 for the AMD Radeon RX 5600 OEM. That is a 23.2% advantage, a substantial margin that places the RX 6650M XT in the 91st percentile of all GPUs tracked, while the RX 5600 OEM sits in the 87th percentile.

The RX 5600 OEM does hold one statistical edge: it has a second benchmark entry, a Geekbench Vulkan score of 53,743, which the RX 6650M XT does not have recorded. However, that absence does not translate into a win, as the database only counts the OpenCL head-to-head result, where the RX 6650M XT wins outright. The RX 5600 OEM's average benchmark score of 58,085 is dragged down by its Vulkan result, while its OpenCL score of 62,427 is its stronger showing. The RX 6650M XT, by contrast, has a single OpenCL score that is both its average and its peak.

In terms of use-case positioning, the data indicates the RX 6650M XT is the stronger compute performer in OpenCL workloads, which often correlate with general-purpose GPU tasks and certain rendering pipelines. The RX 5600 OEM's Vulkan score, while not directly comparable to a matching RX 6650M XT result, suggests it can handle Vulkan-based applications, but the absence of a Vulkan entry for the RX 6650M XT means the database cannot confirm a win for either side in that API. The recorded wins column reflects this: one win for the RX 6650M XT, zero for the RX 5600 OEM.

Architecture Differences

Both GPUs are built by AMD on TSMC's 7 nm process, but they belong to different generations and architectures. The RX 6650M XT uses the Navi 23 chip with RDNA 2.0 architecture, part of the Navi Mobile (RX 6000M) generation. The RX 5600 OEM uses the Navi 10 chip with RDNA 1.0 architecture, part of the Navi (RX 5000) generation. This architectural gap explains much of the performance difference: RDNA 2.0 brings hardware ray tracing support, which the RX 6650M XT implements through 32 dedicated RT cores, while the RX 5600 OEM lists no RT cores at all. The RX 6650M XT also supports DirectX 12 Ultimate (12_2), whereas the RX 5600 OEM is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

The transistor counts and die sizes are close but not identical. The RX 6650M XT packs 11,060 million transistors on a 237 mm² die, yielding a transistor density of 46.7M per mm². The RX 5600 OEM has 10,300 million transistors on a larger 251 mm² die, giving it a lower density of 41.0M per mm². The RX 6650M XT is therefore both more transistor-dense and more area-efficient, which aligns with its newer architecture.

Memory configurations differ significantly. The RX 6650M XT uses 8 GB of GDDR6 on a 128-bit bus, with memory running at 2000 MHz (16 Gbps effective) for 256.0 GB/s of bandwidth. The RX 5600 OEM uses 6 GB of GDDR6 on a wider 192-bit bus, with memory at 1500 MHz (12 Gbps effective) for 288.0 GB/s of bandwidth. The RX 5600 OEM actually has more memory bandwidth, 288.0 GB/s versus 256.0 GB/s, but less total memory capacity. Clock speeds tell the opposite story: the RX 6650M XT runs a base clock of 2068 MHz, a game clock of 2162 MHz, and a boost clock of 2416 MHz, while the RX 5600 OEM runs 1130 MHz base, 1375 MHz game, and 1560 MHz boost. The RX 6650M XT's clocks are dramatically higher across the board.

Both cards share identical shading unit, TMU, and ROP counts: 2048 shading units, 128 TMUs, and 64 ROPs. The RX 6650M XT adds 32 RT cores, which the RX 5600 OEM lacks. The RX 6650M XT is rated for 120 W TDP and is an IGP form factor with no power connectors, while the RX 5600 OEM is a dual-slot card drawing 125 W TDP with a single 8-pin power connector and a 300 W suggested PSU. The RX 6650M XT connects via PCIe 4.0 x8, the RX 5600 OEM via PCIe 4.0 x16. Display outputs also differ: the RX 6650M XT is portable-device dependent, while the RX 5600 OEM offers 1x HDMI 2.0b and 3x DisplayPort 1.4a.

Head-to-Head Benchmarks

The database records one direct comparison between these two GPUs, and it is decisive. In Geekbench OpenCL, the RX 6650M XT scores 76,904 points against the RX 5600 OEM's 62,427 points. The delta is 23.2% in favor of the RX 6650M XT. This is not a marginal win; it is a clear generational leap expressed in raw compute throughput.

Context from the nearest rivals reinforces the gap. The RX 6650M XT sits just 1% behind the NVIDIA GeForce RTX 5090 D, which averages 77,712 points, and 2.6% behind the AMD Radeon RX 6850M XT at 78,940 points. It is also 3.1% ahead of the NVIDIA Tesla P100 PCIe 12 GB (79,396 points is the rival's score, but the delta is listed as -3.1%, meaning the RX 6650M XT trails that card by 3.1%, not leads it; the RX 6650M XT is actually below those rivals). The RX 5600 OEM, meanwhile, sits in a much lower competitive band. Its closest rival is the Intel Arc A570M at 58,239 points, a 0.3% gap, and the AMD Radeon RX 6950 XT at 58,392 points, a 0.5% gap. The RX 5600 OEM's OpenCL score of 62,427 is higher than its average of 58,085, which includes the weaker Vulkan result.

The practical interpretation: the RX 6650M XT delivers roughly a quarter more OpenCL performance than the RX 5600 OEM. That aligns with its higher clocks, newer architecture, and larger memory capacity, despite the RX 5600 OEM's wider memory bus and higher bandwidth. The RX 6650M XT also has a higher pixel rate (154.6 GPixel/s versus 99.84 GPixel/s), a higher texture rate (309.2 GTexel/s versus 199.7 GTexel/s), and higher FP32 throughput (9.896 TFLOPS versus 6.390 TFLOPS). Every raw compute metric in the database favors the RX 6650M XT except memory bandwidth, where the RX 5600 OEM leads with 288.0 GB/s versus 256.0 GB/s.

The Verdict

The data points to a clear choice for most workloads. The RX 6650M XT outperforms the RX 5600 OEM by 23.2% in the only shared benchmark, and it does so while consuming slightly less power (120 W versus 125 W). It also brings modern features the RX 5600 OEM lacks, including hardware ray tracing via 32 RT cores, DirectX 12 Ultimate support, and a newer RDNA 2.0 architecture. Its higher clocks, higher pixel rate, higher texture rate, and higher FP32 throughput all reinforce this lead.

The RX 5600 OEM is not without merits. It offers more memory bandwidth (288.0 GB/s versus 256.0 GB/s), a wider 192-bit bus, and a larger 251 mm² die. It also has a Vulkan benchmark entry, which suggests some Vulkan capability, though no direct comparison exists. For users constrained to a dual-slot card with a standard 8-pin power connector and a 300 W PSU, the RX 5600 OEM fits that form factor. The RX 6650M XT, as an IGP with no power connectors, is designed for portable devices and may not slot into a desktop build at all.

Still, the performance hierarchy is unambiguous. The RX 6650M XT sits at the 91st percentile of all GPUs, while the RX 5600 OEM sits at the 87th. The RX 6650M XT's nearest rivals are high-end cards like the RTX 5090 D and RX 6850M XT, within 1% to 2.6% of its score, while the RX 5600 OEM's nearest rivals are mid-range parts like the Intel Arc A570M and RX 6950 XT, all within 0.8% of its average. In compute-bound tasks, the RX 6650M XT is the superior part. In memory-bandwidth-bound tasks, the RX 5600 OEM's wider bus could help, but the database does not provide a benchmark to confirm that advantage. Based on recorded measurements, the RX 6650M XT is the stronger GPU.
