AMD Radeon RX 7700S vs NVIDIA T550 Mobile Comparison

# Head-to-Head Benchmarks

The benchmark data shows a decisive performance advantage for the AMD Radeon RX 7700S across every shared test. In the Geekbench OpenCL compute benchmark, the RX 7700S scores 62,983 against the NVIDIA T550 Mobile's 35,521, producing a massive 77.3% delta. This is not a marginal gap; it is a near-doubling of raw compute throughput in a workload that stresses general-purpose GPU execution.

The Vulkan test narrows the margin considerably but still favors AMD. The RX 7700S delivers 36,380 points versus 30,801 for the T550 Mobile, a 18.1% advantage. This smaller delta suggests that the NVIDIA part holds up relatively better in graphics-oriented API workloads than in pure compute, though it remains firmly behind.

It is worth contextualizing these scores against each product's broader competitive position. The RX 7700S sits at the 78th percentile among all GPUs in the database, with an average benchmark score of 33,849. Its nearest rivals include the AMD Radeon HD 7950 (33,951, -0.3%), the AMD Radeon RX 480 (33,997, -0.4%), and the NVIDIA GeForce GTX 1060 5 GB (33,694, +0.5%). The T550 Mobile, by contrast, ranks at the 77th percentile with an average score of 33,161, placing it statistically indistinguishable from the NVIDIA GeForce RTX 3050 Mobile (33,170, 0% delta) and the AMD Radeon Pro 570 (33,207, -0.1%).

The head-to-head win count is 2-0 in favor of the RX 7700S. There are no benchmark tests where the T550 Mobile emerges victorious. The data does not show any reverse scenario; both available shared benchmarks point the same direction.

# Where Each One Wins

The RX 7700S wins decisively in compute-heavy applications, as evidenced by the OpenCL result. OpenCL performance is often indicative of non-gaming workloads such as rendering, scientific simulation, and machine learning inference. A 77.3% lead in this metric means the AMD part can finish compute tasks in roughly half the time of the NVIDIA part, assuming linear scaling.

The T550 Mobile's relative strength lies in Vulkan, where its deficit shrinks to 18.1%. Vulkan is a lower-overhead graphics API used in modern games and professional visualization tools. While the NVIDIA part still loses, the narrower gap suggests it is comparatively more competitive in real-time graphics rendering than in raw compute throughput. This aligns with its Turing architecture heritage, which was designed with graphics efficiency in mind.

For pure rasterization workloads, the pixel rate tells a similar story. The RX 7700S achieves 160.0 GPixel/s against 53.28 GPixel/s for the T550 Mobile — a 3x advantage. Texture fill rates follow the same pattern: 320.0 GTexel/s versus 106.6 GTexel/s. These are not close figures; they represent entirely different performance tiers.

The T550 Mobile's single advantage is power consumption. At 23 W TDP, it draws less than a quarter of the RX 7700S's 100 W TDP. For thin-and-light laptops where thermal headroom is scarce, this efficiency profile may be the deciding factor, even if raw performance is far lower.

# Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon RX 7700S is built on the RDNA 3.0 architecture using the Navi 33 chip, codenamed Hotpink Bonefish. It belongs to the Navi Mobile (RX 7000M) generation and is fabricated on TSMC's 6 nm process node. The NVIDIA T550 Mobile uses the Turing architecture with the TU117 chip and belongs to the Quadro Turing-M (Tx000) generation, fabricated on TSMC's 12 nm node.

The process node difference is significant: 6 nm versus 12 nm. This allows the RX 7700S to pack 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2 million per mm². The T550 Mobile contains 4,700 million transistors on a 200 mm² die, achieving only 23.5 million per mm². The AMD chip is roughly three times more transistor-dense, which explains its ability to deliver far higher performance within a similar physical footprint.

Core configurations diverge sharply. The RX 7700S features 2,048 shading units, 128 texture mapping units, 64 raster operation units, and 32 ray tracing cores. The T550 Mobile has 1,024 shading units, 64 TMUs, and 32 ROPs — exactly half in each category — and no dedicated ray tracing hardware. The RX 7700S also supports DirectX 12 Ultimate (12_2), while the T550 Mobile is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Memory subsystems reflect the performance gap. The RX 7700S uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The T550 Mobile has 4 GB of GDDR6 on a 64-bit bus, yielding 96.00 GB/s. The AMD part offers triple the memory capacity and triple the bandwidth. Clock speeds also favor AMD: the RX 7700S boosts to 2500 MHz (with a 2200 MHz game clock) versus 1665 MHz for the T550 Mobile. The RX 7700S also supports PCIe 4.0 x16, while the T550 Mobile uses PCIe 3.0 x16.

# FAQ

Q: Which GPU has the higher FP32 compute throughput?

A: The AMD Radeon RX 7700S delivers 20.48 TFLOPS of FP32 performance, compared to 3.410 TFLOPS for the NVIDIA T550 Mobile. This is a roughly 6x difference in raw single-precision compute.

Q: How do the two GPUs compare in memory bandwidth?

A: The RX 7700S provides 288.0 GB/s of bandwidth from 8 GB of GDDR6 on a 128-bit bus. The T550 Mobile offers 96.00 GB/s from 4 GB of GDDR6 on a 64-bit bus. The AMD part has exactly three times the bandwidth and double the capacity.

Q: Does either GPU support ray tracing?

A: Yes, the RX 7700S includes 32 dedicated ray tracing cores. The T550 Mobile has no ray tracing cores listed in its specifications, indicating no hardware ray tracing support.

Q: What is the power consumption difference?

A: The RX 7700S has a TDP of 100 W, while the T550 Mobile is rated at 23 W. The NVIDIA part consumes less than a quarter of the power of the AMD part.

Q: Which GPU has better Vulkan performance?

A: The RX 7700S scores 36,380 in the Geekbench Vulkan test versus 30,801 for the T550 Mobile, an 18.1% advantage for AMD. Both GPUs support the Vulkan 1.4 API.

Q: Are these GPUs comparable in overall benchmark standing?

A: They are close in percentile rank — 78th for the RX 7700S and 77th for the T550 Mobile — but the average benchmark scores differ by only 688 points (33,849 vs 33,161). However, the head-to-head tests show a much larger gap, indicating that the shared tests may not fully capture the RX 7700S's strengths.

# The Verdict

The data supports only one conclusion for raw performance: the AMD Radeon RX 7700S is in a different class. Its 77.3% OpenCL lead and 18.1% Vulkan lead are backed by architectural advantages in every measured category — shading units, memory bandwidth, pixel rate, texture rate, and FP32 throughput. The RX 7700S also brings ray tracing hardware and DirectX 12 Ultimate support, features entirely absent from the T550 Mobile.

The NVIDIA T550 Mobile's sole argument is power efficiency. At 23 W, it is designed for systems where the 100 W TDP of the RX 7700S would be prohibitive. For a professional user who needs basic graphics acceleration in an ultraportable chassis, the T550 Mobile may be the only viable option. But the performance gap is so large that anyone with thermal headroom to accommodate the RX 7700S should choose it without hesitation.

The production status also matters. The RX 7700S is listed as active, while the T550 Mobile is end-of-life with a successor named (Ampere-MW). From a longevity perspective, the AMD part is the current-generation product, while the NVIDIA part is a legacy offering. Benchmark results indicate that the RX 7700S is the superior choice for compute workloads, gaming, and any task that benefits from memory bandwidth or ray tracing. The T550 Mobile is only appropriate for power-constrained, low-performance scenarios.
