AMD Radeon RX 550X vs AMD Radeon RX 7600M XT Comparison

Head-to-Head Benchmarks

The database records two direct head-to-head comparisons between the AMD Radeon RX 7600M XT and the AMD Radeon RX 550X, and the results are decisive in both cases. The Radeon RX 7600M XT wins every recorded benchmark, with the gap ranging from substantial to overwhelming.

In Geekbench OpenCL, the Radeon RX 7600M XT scores 74,869 points against the RX 550X's 9,662 points. That is a delta of 674.9%, meaning the newer card delivers roughly 7.7 times the raw compute performance in this API. This is not a close contest; it is a generational chasm. The RX 7600M XT's score here also dwarfs its own average benchmark score of 12,710, which suggests OpenCL is a particularly strong workload for this architecture.

In Geekbench Vulkan, the margin narrows but remains lopsided. The RX 7600M XT posts 27,793 points, while the RX 550X manages 11,299 points. The delta is 146%, meaning the RX 7600M XT is about 2.5 times faster in Vulkan. This smaller relative gap compared to OpenCL makes sense given the RX 550X's GCN 4.0 architecture, which still handles Vulkan reasonably well for its class, but the absolute difference is still massive.

Looking at the broader database context, the RX 7600M XT sits at the 52nd percentile among all GPUs, with an average benchmark score of 12,710. Its nearest rivals include the NVIDIA GeForce GTX 670 (average score 12,773, delta -0.5%), the NVIDIA Tesla K20Xm (average score 12,625, delta 0.7%), and the NVIDIA GeForce GTX 590 (average score 12,830, delta -0.9%). This places the RX 7600M XT in a tight cluster of older high-end desktop parts, which is remarkable for a mobile chip.

The RX 550X, by contrast, sits at the 49th percentile with an average benchmark score of 10,481. Its nearest rivals are the NVIDIA Tesla C2075 (average score 10,400, delta 0.8%), the AMD Radeon R9 M275X (average score 10,582, delta -1%), and the AMD Radeon RX 6500M (average score 10,362, delta 1.2%). The RX 550X is essentially at parity with these older or lower-tier parts, landing just below the midpoint of the entire GPU population.

The head-to-head record is 2 wins for the RX 7600M XT and 0 wins for the RX 550X. There are no benchmark categories where the RX 550X takes a lead, whether in compute-heavy OpenCL or graphics-oriented Vulkan.

The Verdict

The data is unambiguous: the AMD Radeon RX 7600M XT is the superior product by every measured metric. If the choice is between these two GPUs, the RX 7600M XT should be selected for any workload where performance matters, including gaming, content creation, or GPU compute. The 674.9% OpenCL advantage and the 146% Vulkan advantage are not marginal differences; they represent entirely different performance tiers.

The RX 550X is an end-of-life product, released in December 2018, based on the GCN 4.0 architecture with a 14 nm process. It produces 1,211.4 GFLOPS of FP32 compute and has 512 shading units. The RX 7600M XT, released in January 2023, delivers 20.23 TFLOPS FP32 with 2,048 shading units. These are not comparable parts in any practical sense.

However, there is one context where the RX 550X makes sense: power-constrained or thermally constrained systems. The RX 550X has a 50 W TDP versus the RX 7600M XT's 120 W TDP. The RX 550X is also a dual-slot card with a 145 mm length, making it physically smaller. For a system with a 250 W suggested PSU, the RX 550X is the only viable option of the two. The RX 7600M XT has no suggested PSU listed, but its power draw is more than double.

Who should pick which? Pick the RX 7600M XT for performance, for modern API support, for ray tracing capability, and for any future-proofing. Pick the RX 550X only if the system's power delivery or physical space cannot accommodate the RX 7600M XT, and if the workload is light enough that the older card's performance is acceptable.

Architecture Differences

The two GPUs come from completely different architectural generations. The RX 7600M XT is built on RDNA 3.0, using the Navi 33 chip with the codename "Hotpink Bonefish." It belongs to the Navi Mobile (RX 7000M) generation. The RX 550X uses GCN 4.0, built on the Lexa chip, and belongs to the Polaris (RX 500X) generation.

The manufacturing process differs significantly. The RX 7600M XT is fabricated on a 6 nm process at TSMC, with 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per mm². The RX 550X uses a 14 nm process at GlobalFoundries, with 2,200 million transistors on a 103 mm² die, giving a density of 21.4 million per mm². The newer process allows more than six times the transistor count in roughly double the die area.

The RX 7600M XT includes 32 ray tracing cores, while the RX 550X has none. This makes the RX 7600M XT capable of hardware-accelerated ray tracing, a feature completely absent from the RX 550X. The RX 7600M XT also supports DirectX 12 Ultimate (12_2), while the RX 550X is limited to DirectX 12 (12_0). Vulkan support is also newer on the RX 7600M XT (version 1.4) compared to the RX 550X (version 1.3). Both support OpenGL 4.6.

The memory subsystem is another major architectural divergence. The RX 7600M XT uses 8 GB of GDDR6 with a 128-bit bus and 288.0 GB/s of bandwidth. The RX 550X uses 4 GB of GDDR5 with a 128-bit bus and 96.00 GB/s of bandwidth. The RX 7600M XT has triple the memory bandwidth despite the same bus width, thanks to the faster GDDR6 standard.

Specification Differences

The core configuration differs by a factor of four. The RX 7600M XT has 2,048 shading units, 128 texture mapping units, and 64 raster operations pipelines. The RX 550X has 512 shading units, 32 TMUs, and 16 ROPs. Every one of these counts is exactly four times higher on the RX 7600M XT.

Clock speeds also favor the newer card, though not as dramatically. The RX 7600M XT has a base clock of 1280 MHz, a boost clock of 2469 MHz, and a game clock of 2023 MHz. The RX 550X has a base clock of 1100 MHz and a boost clock of 1183 MHz, with no game clock listed. The memory clock is 2250 MHz (18 Gbps effective) on the RX 7600M XT versus 1500 MHz (6 Gbps effective) on the RX 550X.

The resulting fill rates and compute throughput are starkly different. The RX 7600M XT achieves 158.0 GPixel/s pixel rate and 316.0 GTexel/s texture rate, with 20.23 TFLOPS FP32 and 40.45 TFLOPS FP16 (2:1 ratio). The RX 550X achieves 18.93 GPixel/s pixel rate and 37.86 GTexel/s texture rate, with 1,211.4 GFLOPS FP32 and the same 1,211.4 GFLOPS FP16 (1:1 ratio). The FP32 compute gap is roughly 16.7 times.

Power and physical specifications differ as well. The RX 7600M XT has a 120 W TDP and is listed as an IGP (integrated graphics processor) slot width with no power connectors and no suggested PSU. The RX 550X has a 50 W TDP, is dual-slot, has no power connectors, and lists a 250 W suggested PSU. The RX 550X measures 145 mm (5.7 inches) in length. The RX 7600M XT's dimensions are not listed. The bus interface is PCIe 4.0 x16 on the RX 7600M XT versus PCIe 3.0 x8 on the RX 550X.

Display outputs differ too: the RX 7600M XT is "Portable Device Dependent," while the RX 550X offers 1x DVI, 1x HDMI 2.0b, and 1x DisplayPort 1.4a.

Where Each One Wins

The RX 7600M XT wins in every recorded benchmark category. Its 2,048 shading units, 32 ray tracing cores, and 20.23 TFLOPS FP32 throughput make it the clear choice for modern gaming, especially titles that leverage DirectX 12 Ultimate features like ray tracing. The 8 GB GDDR6 frame buffer with 288.0 GB/s bandwidth supports high-resolution textures and demanding visual effects. The 6 nm process and RDNA 3.0 architecture deliver the performance to handle contemporary workloads without compromise.

The RX 550X wins in scenarios defined by constraints rather than performance. Its 50 W TDP means it can fit into systems with limited cooling or power delivery, and its 145 mm length makes it suitable for compact chassis. The 250 W suggested PSU requirement is modest, so it can be paired with low-wattage power supplies that would not support the RX 7600M XT. The dual-slot design and PCIe 3.0 x8 interface also make it compatible with older motherboards.

For compute workloads measured in the database, the RX 7600M XT's OpenCL score of 74,869 is in a different league from the RX 550X's 9,662. For Vulkan gaming, the 27,793 versus 11,299 margin still favors the RX 7600M XT by more than double. The only practical reason to choose the RX 550X is if the system physically or electrically cannot handle the RX 7600M XT, or if the workload is so light that the performance difference does not matter. In all other cases, the data points to the RX 7600M XT as the superior part.
