AMD Radeon RX 7700 XT vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for the AMD Radeon RX 7700 XT versus the NVIDIA N1X 40SM. The Radeon RX 7700 XT has a comprehensive set of recorded scores across multiple test suites, while the N1X 40SM has no benchmark entries in the database. This makes a direct numerical comparison impossible from the recorded data alone.

What can be established is the Radeon RX 7700 XT's standing within the broader GPU landscape. Its average benchmark score is 22,549, placing it at the 67th percentile of all GPUs in the database. The nearest recorded rival is the NVIDIA GeForce RTX 2080 with an average score of 22,895, which is 1.5% ahead of the RX 7700 XT. The AMD Radeon RX 5700 sits 1.7% behind at 22,170. The NVIDIA GeForce RTX 5060 Mobile scores 22,435, a 0.5% difference, and the RTX 4060 Mobile scores 22,729, 0.8% ahead of the RX 7700 XT. These margins are narrow, indicating the RX 7700 XT operates in a tightly contested performance band.

In individual test results, the RX 7700 XT shows its strongest showing in Geekbench OpenCL with 138,383 points, followed by PassMark G3D at 22,547 and PassMark GPU Compute at 12,912.

The Verdict

The data supports a clear choice for most users: the AMD Radeon RX 7700 XT is the only one of the two with recorded performance evidence. It has an average benchmark score of 22,549, sits at the 67th percentile of all GPUs, and competes within 1.5% of the NVIDIA GeForce RTX 2080. The NVIDIA N1X 40SM has no benchmark scores, no rivals, and a placeholder 50th percentile. Any builder seeking a discrete GPU with verified results should select the RX 7700 XT based on the database evidence.

The N1X 40SM is an integrated graphics processor (IGP) with a 382 mm² die, 5,120 shading units, and 160 tensor cores. Its 128 GB LPDDR5X memory allocation and 273.2 GB/s bandwidth are unusual for an IGP, but the lack of API support entries and zero benchmark data means its real-world performance cannot be assessed. The RX 7700 XT, with its 12 GB GDDR6, 432.0 GB/s bandwidth, and full API support, is the practical pick for gaming and general GPU workloads.

Specification Differences

The two GPUs differ across nearly every specification field. The RX 7700 XT is a discrete card with a dual-slot form factor, 267 mm length, 135 mm height, and 50 mm width, requiring two 8-pin power connectors and a 550 W suggested PSU. The N1X 40SM is listed as IGP slot width with no power connectors and no suggested PSU.

Memory differs substantially: 12 GB GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth for the RX 7700 XT versus 128 GB LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth for the N1X 40SM. Clock speeds also diverge, with the RX 7700 XT running a 1435 MHz base and 2544 MHz boost, while the N1X 40SM runs a 741 MHz base and 2346 MHz boost.

The RX 7700 XT has 3,456 shading units, 216 TMUs, and 96 ROPs. The N1X 40SM has 5,120 shading units, 320 TMUs, and 40 ROPs. The RX 7700 XT has 54 RT cores and no tensor cores; the N1X 40SM has 40 RT cores and 160 tensor cores. The RX 7700 XT uses a PCIe 4.0 x16 interface; the N1X 40SM uses PCIe 5.0 x16.

Display outputs differ: the RX 7700 XT offers 1x HDMI 2.1, 2x DisplayPort 2.1, and 1x USB Type-C, while the N1X 40SM offers only 1x HDMI. The RX 7700 XT is rated at 245 W TDP; the N1X 40SM TDP is unknown.

Architecture Differences

The RX 7700 XT is built on the Navi 32 chip using RDNA 3.0 architecture, part of the Navi III (RX 7000) generation, with the codename Wheat Nas. It uses a 5 nm process from TSMC, contains 28,100 million transistors on a 346 mm² die, and has a transistor density of 81.2M per mm². Its predecessor is Navi II and its successor is Navi IV. The RX 7700 XT was released in 2023.

The N1X 40SM uses the GB20B chip with Blackwell 2.0 architecture, part of the Blackwell IGP (N1x) generation. It also uses a 5 nm TSMC process but has an unknown transistor count on a larger 382 mm² die, with no transistor density listed. It has no codename, predecessor, or successor recorded, and its release date is listed as 2026. The N1X 40SM is an integrated processor, not a discrete add-in card.

The RX 7700 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists N/A for all three APIs. The RX 7700 XT has FP32 and FP16 compute of 35.17 TFLOPS each, while the N1X 40SM has 24.02 TFLOPS for both. The RX 7700 XT has a higher pixel rate (244.2 GPixel/s) but a lower texture rate (549.5 GTexel/s) compared to the N1X 40SM (93.84 GPixel/s and 750.7 GTexel/s).

Where Each One Wins

The AMD Radeon RX 7700 XT wins in every measurable performance category because the database contains no benchmark results for the N1X 40SM. Its 35.17 TFLOPS FP32 compute exceeds the N1X 40SM's 24.02 TFLOPS. Its pixel rate of 244.2 GPixel/s is more than double the N1X 40SM's 93.84 GPixel/s. Its memory bandwidth of 432.0 GB/s is substantially higher than the N1X 40SM's 273.2 GB/s.

The N1X 40SM wins in structural specifications: 128 GB memory capacity versus 12 GB, 5,120 shading units versus 3,456, 320 TMUs versus 216, 160 tensor cores versus none, a 256-bit memory bus versus 192-bit, a larger die at 382 mm² versus 346 mm², and PCIe 5.0 x16 versus PCIe 4.0 x16. Its texture rate of 750.7 GTexel/s is higher than the RX 7700 XT's 549.5 GTexel/s.

For gaming and discrete GPU workloads, the RX 7700 XT is the only option with verified performance data. For applications requiring massive memory capacity or tensor core functionality, the N1X 40SM offers those features on paper, but without benchmark scores its practical capability remains unverified. The RX 7700 XT's 67th percentile ranking and competitive standing against the RTX 2080 and RTX 4060 Mobile indicate it is a capable performer within its recorded performance band.
