AMD Radeon RX 7600 XT vs NVIDIA N1 20SM Comparison

Where Each One Wins

The AMD Radeon RX 7600 XT and the NVIDIA N1 20SM occupy entirely different performance domains, as reflected in their recorded data. The RX 7600 XT is a discrete graphics card with a full suite of benchmark results, while the N1 20SM is an integrated graphics processor (IGP) with no recorded benchmark scores. The RX 7600 XT wins every measurable category by default, but the interesting split is not between these two parts in direct competition; it is in what each is designed to do.

The RX 7600 XT delivers a complete desktop experience: it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it has active production status with a release date in early 2024. Its benchmark results show it sits at the 60th percentile among all GPUs, with an average benchmark score of 17,083. The N1 20SM, by contrast, has no API support listed (DirectX, OpenGL, and Vulkan are all marked N/A), no benchmark scores, and a 50th percentile ranking. The N1 20SM is built for a different role: it is an IGP with a PCIe 5.0 x16 interface, 128 GB of LPDDR5X memory, and a 256-bit bus, which points toward integrated or embedded use rather than standalone gaming or workstation tasks.

Where each one wins is therefore a question of application. The RX 7600 XT wins in any scenario requiring a dedicated graphics card with established driver support and measurable compute performance. The N1 20SM wins in scenarios requiring a massive memory pool (128 GB) and a very wide memory bus (256-bit) within an integrated form factor, with no power connectors and a dual-slot footprint absent entirely. The N1 20SM also uses a more advanced process node (5 nm versus 6 nm) and a newer architecture (Blackwell 2.0 versus RDNA 3.0), but those architectural advantages do not translate into benchmark wins because no benchmarks are recorded for it.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The RX 7600 XT uses the Navi 33 chip with RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi III (RX 7000) generation. Its predecessor is Navi II and its successor is Navi IV. The N1 20SM uses the GB20B chip with Blackwell 2.0 architecture and belongs to the Blackwell IGP (N1x) generation. It has no listed predecessor or successor.

The process nodes differ: the RX 7600 XT is fabricated on TSMC's 6 nm node, while the N1 20SM uses TSMC's 5 nm node. The transistor counts are not directly comparable, as the RX 7600 XT lists 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per mm², while the N1 20SM lists its transistor count as unknown but has a larger die size of 382 mm². The N1 20SM die is nearly twice the size of the RX 7600 XT die, despite having no confirmed transistor figure.

Core configurations differ substantially. The RX 7600 XT has 2,048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The N1 20SM has 2,560 shading units, 160 TMUs, 24 ROPs, 20 ray tracing cores, and 80 tensor cores. The RX 7600 XT has no tensor cores listed, while the N1 20SM includes 80 of them. The shading unit count favors the N1 20SM by 512 units, and the TMU count favors it by 32 units, but the ROP count heavily favors the RX 7600 XT by 40 units. The pixel rate reflects this: the RX 7600 XT delivers 176.3 GPixel/s versus the N1 20SM's 56.30 GPixel/s.

Clock speeds also diverge. The RX 7600 XT has a base clock of 1980 MHz, a boost clock of 2755 MHz, and a game clock of 2470 MHz. The N1 20SM has a base clock of 741 MHz and a boost clock of 2346 MHz, with no game clock listed. Memory clocks differ as well: the RX 7600 XT runs memory at 2250 MHz (18 Gbps effective), while the N1 20SM runs at 1067 MHz (8.5 Gbps effective).

Head-to-Head Benchmarks

The head-to-head benchmark list is empty, and the win counts for both items are zero. This means no direct comparative tests were recorded between the RX 7600 XT and the N1 20SM. However, the RX 7600 XT has its own benchmark results, and those can be interpreted against its nearest rivals in the database.

The RX 7600 XT scores 2,348 in 3DMark Steel Nomad DX12, 92,426 in Geekbench OpenCL, and 48,366 in Geekbench Vulkan. In Passmark tests, it scores 85 in DirectX 10, 167 in DirectX 11, 65 in DirectX 12, 228 in DirectX 9, 1,030 in G2D, 17,132 in G3D, and 8,987 in GPU compute. The average benchmark score is 17,083.

Against its nearest rivals, the RX 7600 XT is essentially tied with the NVIDIA GeForce GTX 690, which has an average score of 17,037, a delta of 0.3 percent. It is also nearly tied with the AMD Radeon HD 7970M, which scores 17,019, a delta of 0.4 percent. The NVIDIA GeForce RTX 3070 scores 17,208, which is 0.7 percent higher than the RX 7600 XT, meaning the RX 7600 XT trails that card by a small margin. The NVIDIA Tesla M4 scores 16,932, which is 0.9 percent lower than the RX 7600 XT.

These deltas are all within a single percentage point, indicating that the RX 7600 XT performs in a very tight band around these four cards. The data shows it is marginally ahead of the GTX 690, the HD 7970M, and the Tesla M4, and marginally behind the RTX 3070. None of these differences are large enough to represent a clear generational or tier advantage. The RX 7600 XT's 60th percentile ranking among all GPUs places it just above the midpoint of the database's distribution.

For the N1 20SM, no benchmark scores exist, so no head-to-head comparison is possible. Its average benchmark score is listed as 0, and its percentile is 50, which likely reflects its position as an IGP rather than a tested discrete part.

Specification Differences

The two parts differ in nearly every specification field. The RX 7600 XT is manufactured by AMD, while the N1 20SM is by NVIDIA. The RX 7600 XT uses the Navi 33 chip, the N1 20SM uses the GB20B chip. The RX 7600 XT has a 6 nm process node, the N1 20SM a 5 nm node. Die size is 204 mm² for the RX 7600 XT and 382 mm² for the N1 20SM. Transistor count is 13,300 million for the RX 7600 XT and unknown for the N1 20SM.

Memory configurations are starkly different. The RX 7600 XT has 16 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s bandwidth. The N1 20SM has 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s bandwidth. The N1 20SM has eight times the memory capacity but slightly lower bandwidth.

Clock speeds differ across the board. The RX 7600 XT has base, boost, and game clocks of 1980 MHz, 2755 MHz, and 2470 MHz respectively. The N1 20SM has base and boost clocks of 741 MHz and 2346 MHz, with no game clock. Memory clocks are 2250 MHz (18 Gbps effective) for the RX 7600 XT and 1067 MHz (8.5 Gbps effective) for the N1 20SM.

Compute resources differ: 2,048 shading units for the RX 7600 XT versus 2,560 for the N1 20SM, 128 TMUs versus 160, 64 ROPs versus 24, 32 RT cores versus 20, and no tensor cores versus 80. The RX 7600 XT has a pixel rate of 176.3 GPixel/s versus 56.30 GPixel/s for the N1 20SM. Texture rates are 352.6 GTexel/s versus 375.4 GTexel/s, favoring the N1 20SM. FP32 performance is 22.57 TFLOPS for the RX 7600 XT versus 12.01 TFLOPS for the N1 20SM. FP16 figures are identical to FP32 for both, at 22.57 TFLOPS and 12.01 TFLOPS respectively.

Physical and power characteristics diverge as well. The RX 7600 XT has a TDP of 190 W, a dual-slot form factor, one 8-pin power connector, and a suggested PSU of 450 W. The N1 20SM has an unknown TDP, is an IGP, has no power connectors, and no suggested PSU. The RX 7600 XT uses a PCIe 4.0 x8 interface, while the N1 20SM uses PCIe 5.0 x16. Display outputs are 1x HDMI 2.1a and 3x DisplayPort 2.1 for the RX 7600 XT, versus just 1x HDMI for the N1 20SM.

The RX 7600 XT lists API support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists N/A for all three APIs. The RX 7600 XT has dimensions of 204 mm length and 115 mm height; the N1 20SM has no dimensions listed. The RX 7600 XT has a launch MSRP of 329 USD; the N1 20SM has no launch MSRP.
