AMD Radeon RX 7600M XT vs NVIDIA N1X 48SM Comparison

The Verdict

The recorded data presents an uneven comparison. The AMD Radeon RX 7600M XT is a shipping, benchmarked mobile GPU with a full set of measured scores. The NVIDIA N1X 48SM is an active Blackwell IGP with no benchmark entries in the database, giving it an average benchmark score of zero and an empty nearest rivals list. For anyone needing immediate, verified performance data, the AMD part is the only option with substance. The N1X 48SM, while architecturally newer and equipped with a massive memory pool, cannot be assessed for real-world speed from the current measurements. The data indicates the RX 7600M XT occupies the 52nd percentile among all GPUs, while the N1X 48SM sits at the 50th percentile based on specifications alone, not on any executed test. Choose the RX 7600M XT if benchmark confirmation matters. Choose the N1X 48SM only if its architectural traits and unified memory capacity are the priority, accepting that its performance profile is unquantified.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing nodes. The AMD Radeon RX 7600M XT is built on RDNA 3.0 with the Navi 33 chip, codenamed Hotpink Bonefish. It belongs to the Navi Mobile generation, part of the RX 7000M series. Its process node is 6 nm at TSMC. The NVIDIA N1X 48SM uses the Blackwell 2.0 architecture with the GB20B chip and belongs to the Blackwell IGP generation, labeled N1x. Its process node is 5 nm, also at TSMC.

Transistor counts and die sizes differ substantially. The RX 7600M XT packs 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm². The N1X 48SM has an unknown transistor count but a larger die at 382 mm². The die size difference of 178 mm² reflects the N1X 48SM's higher unit counts across most compute blocks.

The compute resource distribution is notably different. The RX 7600M XT has 2048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The N1X 48SM has 6144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The N1X 48SM triples the shading units and TMUs, but has fewer ROPs. The RX 7600M XT has no tensor core entries, while the N1X 48SM includes 192, reflecting its Blackwell lineage.

Feature support diverges on the API front. The RX 7600M XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM records DirectX, OpenGL, and Vulkan as N/A. This is a significant practical difference for software compatibility, as the AMD part is measured against current graphics APIs while the NVIDIA part carries no listed API support in the database.

Specification Differences

Clock speeds separate the two clearly. The RX 7600M XT has a base clock of 1280 MHz and a boost clock of 2469 MHz, with a game clock of 2023 MHz. The N1X 48SM has a base clock of 741 MHz and a boost clock of 2346 MHz. The AMD part runs 539 MHz higher at base and 123 MHz higher at boost. Memory clocks also differ: the RX 7600M XT runs at 2250 MHz with 18 Gbps effective, while the N1X 48SM runs at 1067 MHz with 8.5 Gbps effective.

Memory configuration is a major differentiator. The RX 7600M XT has 8 GB of GDDR6 on a 128 bit bus with 288.0 GB/s bandwidth. The N1X 48SM has 128 GB of LPDDR5X on a 256 bit bus with 273.2 GB/s bandwidth. The NVIDIA part has 120 GB more memory and a wider bus, but slightly lower bandwidth, 14.8 GB/s less than the AMD part.

Rates and throughput figures diverge. The RX 7600M XT achieves a pixel rate of 158.0 GPixel/s and a texture rate of 316.0 GTexel/s. The N1X 48SM achieves 112.6 GPixel/s and 900.9 GTexel/s. The AMD part has a 45.4 GPixel/s pixel rate advantage, while the NVIDIA part has a 584.9 GTexel/s texture rate advantage. FP32 compute favors the N1X 48SM at 28.83 TFLOPS versus 20.23 TFLOPS. FP16 also differs: the RX 7600M XT reaches 40.45 TFLOPS at a 2:1 ratio, while the N1X 48SM delivers 28.83 TFLOPS at 1:1.

Both use an IGP slot width and have no power connectors. The RX 7600M XT has a 120 W TDP, while the N1X 48SM has an unknown TDP. The bus interface differs: PCIe 4.0 x16 for the AMD part, PCIe 5.0 x16 for the NVIDIA part. Display outputs are portable device dependent for the RX 7600M XT, while the N1X 48SM lists 1x HDMI. The AMD part was released on 2023-01-03, the NVIDIA part on 2026-05-31. Both are marked Active in production status.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two GPUs. The winsA and winsB counters are both zero. The RX 7600M XT has its own benchmark suite recorded, while the N1X 48SM has an empty benchmarks array. This means any direct comparison of measured performance is impossible from the current data.

The RX 7600M XT's recorded scores provide a baseline for its standing. In 3DMark Steel Nomad DX12 it scores 2048. Geekbench OpenCL returns 74869, and Geekbench Vulkan returns 27793. Passmark results include 13907 in G3D, 7140 in GPU compute, 894 in G2D, 175 in DirectX 9, 137 in DirectX 11, 76 in DirectX 10, and 58 in DirectX 12. Its average benchmark score across the suite is 12710.

The N1X 48SM has no such data. Its percentileVsAllGpus is 50, compared to the RX 7600M XT's 52. The RX 7600M XT's nearest rivals show how closely it sits to older discrete parts: 0.5% behind the GeForce GTX 670, 0.7% ahead of the Tesla K20Xm, and 0.9% behind both the GeForce GTX 590 and the Radeon Pro 455. These deltas are small, indicating the RX 7600M XT performs in a narrow band around those cards. The N1X 48SM has no nearest rivals listed, reinforcing its status as an unmeasured part.

Where Each One Wins

The RX 7600M XT wins in every category where actual performance data exists. It has a higher average benchmark score, 12710 versus 0. It records real scores across DirectX, OpenCL, and Vulkan tests, while the N1X 48SM has none. Its pixel rate of 158.0 GPixel/s exceeds the N1X 48SM's 112.6 GPixel/s, making it faster at fill-rate bound work. Its memory bandwidth of 288.0 GB/s is higher than the N1X 48SM's 273.2 GB/s, which can benefit memory-heavy tasks despite the smaller 8 GB capacity. Its boost clock of 2469 MHz is higher than the N1X 48SM's 2346 MHz. Its DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support give it a clear software compatibility edge over the N1X 48SM's N/A entries.

The N1X 48SM wins on raw specification counts. Its 6144 shading units are triple the RX 7600M XT's 2048. Its 384 TMUs are triple the 128 on the AMD part, producing a texture rate of 900.9 GTexel/s versus 316.0 GTexel/s. Its FP32 throughput of 28.83 TFLOPS exceeds the RX 7600M XT's 20.23 TFLOPS by 8.60 TFLOPS. Its 128 GB of LPDDR5X memory is 16 times the RX 7600M XT's 8 GB, and its 256 bit bus is double the width. It has 48 ray tracing cores to the RX 7600M XT's 32, and it has 192 tensor cores where the AMD part has none. It also uses a newer PCIe 5.0 x16 interface versus PCIe 4.0 x16, and a 5 nm process node versus 6 nm. The N1X 48SM's 382 mm² die is 178 mm² larger than the RX 7600M XT's 204 mm² die.

For use-case planning, the RX 7600M XT suits scenarios requiring verified performance, established driver API support, and higher pixel throughput with faster memory bandwidth. The N1X 48SM suits scenarios where massive memory capacity, high texture throughput, FP32 compute, and tensor core availability matter more than measured results. The lack of benchmark data for the N1X 48SM means its specification advantages remain theoretical until tests are recorded.
