AMD Radeon RX 7800M vs NVIDIA T550 Mobile Comparison

Head-to-Head Benchmarks

The recorded data is unambiguous: the AMD Radeon RX 7800M dominates the NVIDIA T550 Mobile in every shared benchmark test. In the two head-to-head results available, the AMD part wins both by a wide margin, with no benchmark wins recorded for the NVIDIA T550 Mobile.

Starting with Geekbench OpenCL, the AMD Radeon RX 7800M scores 120,778 points against 35,521 points for the NVIDIA T550 Mobile. That is a delta of -70.6 percent from the AMD card's perspective, meaning the T550 delivers less than a third of the RX 7800M's raw compute throughput in this test. The gap is even more pronounced in Geekbench Vulkan, where the RX 7800M hits 126,668 points versus 30,801 points for the T550 Mobile, a -75.7 percent delta. In practical terms, the AMD card is roughly four times faster in Vulkan workloads, a massive separation for any two mobile GPUs.

The average benchmark score, which aggregates all recorded tests for each part, reinforces the same story. The RX 7800M carries an average score of 27,883, while the T550 Mobile averages 33,161. That the T550's average is higher despite losing both head-to-head tests may seem counterintuitive, but it reflects the fact that the two GPUs were tested under different benchmark suites. The T550's average is built from only two Geekbench results, both of which are strong for its class. The RX 7800M's average includes a broader set of tests, including Passmark DirectX 9, 10, 11, and 12 runs, plus 3DMark Steel Nomad DX12, which pull its mean downward. The head-to-head comparison remains the cleanest signal: wherever both chips ran the same test, the RX 7800M won by 70 percent or more.

Percentile rankings place the T550 Mobile at the 77th percentile among all GPUs in the database, while the RX 7800M sits at the 73rd percentile. So even though the AMD card is far faster in direct comparisons, its broader test profile includes legacy and compute workloads where it does not dominate as thoroughly. The T550's percentile is buoyed by its narrow, high-scoring Geekbench results. In any direct matchup, however, the RX 7800M is the clear performance leader.

Architecture Differences

The two GPUs come from different architectural generations and process technologies. The NVIDIA T550 Mobile is built on the Turing architecture with the TU117 chip, manufactured on a 12 nm process at TSMC. The AMD Radeon RX 7800M uses the RDNA 3.0 architecture with the Navi 32 chip, also fabricated by TSMC but on a 5 nm node. That process difference is substantial: the RX 7800M packs 28,100 million transistors into a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter. The T550 Mobile, by contrast, contains 4,700 million transistors on a 200 mm² die, for a density of 23.5 million per square millimeter. The AMD chip is roughly six times denser in transistor packing, a direct result of the newer node.

Core counts diverge sharply. The T550 Mobile has 1,024 shading units, 64 texture mapping units, and 32 ROPs. The RX 7800M fields 3,840 shading units, 240 TMUs, and 96 ROPs. That is 3.75 times more shaders, 3.75 times more TMUs, and three times more ROPs. The AMD card also includes 60 ray tracing cores, a feature entirely absent from the T550 Mobile's spec sheet. Neither card lists tensor cores, though the T550's Turing architecture typically includes them in other variants; the database records none for this specific SKU.

Clock speeds favor the AMD part as well. The RX 7800M runs a base clock of 1295 MHz, a game clock of 2145 MHz, and a boost clock of 2335 MHz. The T550 Mobile starts at 1065 MHz base and boosts to 1665 MHz. Memory clocks differ by an even larger factor: the RX 7800M's memory runs at 2250 MHz with 18 Gbps effective speed, while the T550's memory is at 1500 MHz with 12 Gbps effective. The memory subsystem itself is completely different in scale. The RX 7800M has 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s of bandwidth. The T550 Mobile has 4 GB of GDDR6 on a 64-bit bus, for 96.00 GB/s. That is a 4.5 times bandwidth advantage for the AMD card.

Pixel and texture rates reflect the core and clock differences. The RX 7800M achieves 224.2 GPixel/s and 560.4 GTexel/s. The T550 Mobile manages 53.28 GPixel/s and 106.6 GTexel/s. Floating-point throughput is similarly lopsided: the RX 7800M delivers 35.87 TFLOPS FP32 and the same 35.87 TFLOPS FP16 at a 1:1 ratio. The T550 Mobile offers 3.410 TFLOPS FP32 and 6.820 TFLOPS FP16 at a 2:1 ratio. The AMD card is roughly 10.5 times faster in FP32 and about 5.3 times faster in FP16.

Power consumption tells a different story. The T550 Mobile is rated at 23 W TDP, making it a low-power part suited for thin-and-light systems. The RX 7800M draws 180 W TDP, a 7.8 times higher power envelope. Both use integrated graphics packages (IGP slot width) with no power connectors listed, and both have portable-device-dependent display outputs. The T550 uses PCIe 3.0 x16; the RX 7800M uses PCIe 4.0 x16.

API support also differs. The T550 Mobile supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The RX 7800M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The DirectX 12_2 feature level on the AMD card enables hardware ray tracing and mesh shaders, consistent with its 60 RT cores. The T550's 12_1 level is a generation older.

Where Each One Wins

The AMD Radeon RX 7800M wins unequivocally in raw performance. Every benchmark result in the head-to-head comparison favors it, and its architectural advantages in shader count, memory bandwidth, and clock speed make it the stronger choice for any GPU-bound workload. The data shows a 240 percent advantage in OpenCL and a 311 percent advantage in Vulkan. For gaming, content creation, or compute tasks that scale with shading units and memory throughput, the RX 7800M is the clear pick.

The NVIDIA T550 Mobile has no benchmark wins in this comparison, but its strengths lie elsewhere. At 23 W TDP, it draws a fraction of the RX 7800M's 180 W. For systems where thermal headroom and battery life are paramount, the T550 is the practical option. Its 77th percentile ranking also indicates that, within its own low-power class, it performs respectably; the nearest rivals in the database include the NVIDIA GeForce RTX 3050 Mobile at 33,170 average score (0 percent delta) and the NVIDIA T600 Mobile at 32,849 (1 percent delta). The T550 slots right in line with those parts, meaning it is competitive among low-power mobile GPUs even if it cannot touch the RX 7800M.

The RX 7800M's nearest rivals tell a different story. Its average score of 27,883 places it near the AMD Radeon Pro Vega 20 (27,839, 0.2 percent delta) and the AMD Radeon Pro W5500X (27,973, -0.3 percent delta). These are workstation-class discrete GPUs, not integrated low-power parts. The RX 7800M is competing in a much higher performance tier, which is exactly where its hardware specifications place it. The T550 Mobile is an entry-level mobile part; the RX 7800M is a high-end mobile part. The benchmark data confirms that hierarchy.

For users who need maximum frame rates or compute throughput in a laptop, the RX 7800M is the only choice between these two. For users who need a GPU that sips power and fits into ultraportable designs, the T550 Mobile has a role, but it is not a performance role. The database records no scenario where the T550 wins a benchmark against the RX 7800M.
