AMD Radeon RX 7650 GRE vs NVIDIA N1 20SM Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the AMD Radeon RX 7650 GRE and the NVIDIA N1 20SM. The database lists zero shared test runs, so any comparison relies on the individual benchmark scores and aggregate performance metrics available for each part.

The AMD Radeon RX 7650 GRE has two recorded benchmark entries. In 3DMark Steel Nomad DX12, it scores 2336 points. In Geekbench OpenCL, it scores 83109 points. These results place the card at the 83rd percentile among all GPUs tracked in the database, with an average benchmark score of 42723.

The NVIDIA N1 20SM has no recorded benchmark entries. Its average benchmark score is listed as 0, and it sits at the 50th percentile among all GPUs. The absence of test data means the database cannot establish a measured performance relationship between these two products. The AMD card's nearest rivals, all with average scores within 1.3% of its own, show how tightly clustered its performance envelope is: the NVIDIA GeForce RTX 4070 SUPER averages 43223 (1.2% higher), the NVIDIA Quadro M6000 24 GB averages 43262 (1.2% higher), the NVIDIA GeForce RTX 5050 Mobile averages 43268 (1.3% higher), and the NVIDIA Quadro M6000 averages 43301 (1.3% higher). Every one of these rivals edges out the RX 7650 GRE by a small margin, confirming that the AMD card competes in a narrow performance band rather than holding a decisive lead over any nearby part.

Because the N1 20SM lacks benchmark data, no percentage deltas can be calculated between the two cards. The database indicates zero wins for either product in head-to-head testing. This is not a statement of equivalence; it is simply a reflection of missing measurement data for the NVIDIA part.

Architecture Differences

The two GPUs come from different manufacturers, different architectures, and different market segments.

AMD uses the Navi 33 chip, built on RDNA 3.0 architecture with the codename "Hotpink Bonefish." It belongs to the Navi III (RX 7000) generation and is manufactured on a 6 nm process at TSMC. The die measures 204 mm² and packs 13,300 million transistors, yielding a transistor density of 65.2 million per mm². The chip is fabricated with a base clock of 1720 MHz, a boost clock of 2695 MHz, and a game clock of 2350 MHz. Memory runs at 2250 MHz with 18 Gbps effective data rate.

NVIDIA's N1 20SM uses the GB20B chip, built on Blackwell 2.0 architecture and belonging to the Blackwell IGP (N1x) generation. It is manufactured on a 5 nm process at TSMC. The die is larger at 382 mm², but the transistor count is listed as unknown, so no density figure can be derived. The base clock is 741 MHz and the boost clock is 2346 MHz, with memory at 1067 MHz and 8.5 Gbps effective.

The memory subsystems differ substantially. The AMD card carries 8 GB of GDDR6 on a 128-bit bus, providing 288.0 GB/s of bandwidth. The NVIDIA part carries 128 GB of LPDDR5X on a 256-bit bus, providing 273.2 GB/s of bandwidth. Despite having twice the bus width, the N1 20SM's slower memory clocks result in slightly lower bandwidth than the RX 7650 GRE.

Compute resources are split in interesting ways. The AMD card has 2048 shading units, 128 texture mapping units, 64 raster output pipelines, and 32 ray tracing cores. It has no tensor cores. The NVIDIA part has 2560 shading units, 160 texture mapping units, only 24 raster output pipelines, 20 ray tracing cores, and 80 tensor cores. The N1 20SM has more shaders and TMUs, but the RX 7650 GRE has nearly triple the ROP count.

The measured throughput numbers reflect these configurations. AMD's pixel rate is 172.5 GPixel/s versus 56.30 GPixel/s for NVIDIA, a direct consequence of the ROP disparity. Texture rate favors the NVIDIA part: 375.4 GTexel/s versus 345.0 GTexel/s. FP32 compute goes the other way: 22.08 TFLOPS for AMD versus 12.01 TFLOPS for NVIDIA. Both cards list FP16 at the same rate as FP32, a 1:1 ratio.

Power and physical characteristics diverge sharply. The RX 7650 GRE has a TDP of 170 W, uses a dual-slot cooler, requires a single 8-pin power connector, and recommends a 450 W power supply. It connects via PCIe 4.0 x8 and offers 1x HDMI 2.1a plus 3x DisplayPort 2.1 outputs. Its dimensions are 204 mm in length and 115 mm in height. The N1 20SM is an integrated graphics processor with no TDP listed, no power connectors, no slot width beyond its IGP designation, and no suggested power supply. It uses PCIe 5.0 x16 and offers a single HDMI output. The API support also differs: AMD lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while NVIDIA's API support is listed as N/A across the board.

The Verdict

The data supports a clear split based on intended use case.

For discrete gaming and general desktop GPU workloads, the AMD Radeon RX 7650 GRE is the only one of the two with measurable performance data. Its 83rd percentile ranking and average benchmark score of 42723 demonstrate that it operates in a well-established performance tier, one that lands within 1.3% of GPUs like the GeForce RTX 4070 SUPER and the RTX 5050 Mobile. The card's 22.08 TFLOPS FP32 throughput, 172.5 GPixel/s pixel rate, and 288.0 GB/s memory bandwidth give it a balanced profile for rasterization-heavy tasks. Its 8 GB GDDR6 allocation is modest, but the card is an active product with a release date in the RX 7000 series lineage.

For integrated or embedded applications where the GPU shares the system with a CPU, the NVIDIA N1 20SM presents a different profile. Its 128 GB LPDDR5X memory capacity is enormous compared to the AMD card, and its 80 tensor cores suggest a design aimed at AI-adjacent workloads rather than traditional graphics. However, the absence of any benchmark scores means the database cannot confirm its real-world performance. The 50th percentile ranking, combined with an average score of 0, indicates that the part has not been validated through the same testing pipeline. Its API support is listed as N/A, which limits its usefulness for standard graphics applications. The 24 ROPs and 56.30 GPixel/s pixel rate are far below the AMD card's figures, so any workload dependent on fill rate would favor the RX 7650 GRE.

Strictly from the recorded data, the RX 7650 GRE is the choice for users who need proven, measured graphics performance in a discrete card. The N1 20SM is the choice only for scenarios that require its unique combination of 128 GB unified memory, tensor core count, and integrated form factor, with the understanding that its graphics capabilities are unverified.

Where Each One Wins

The AMD Radeon RX 7650 GRE wins in every category where direct measurements exist. Its FP32 throughput of 22.08 TFLOPS is nearly double the N1 20SM's 12.01 TFLOPS. Its pixel rate of 172.5 GPixel/s is more than three times the NVIDIA part's 56.30 GPixel/s, driven by 64 ROPs versus 24. Its memory bandwidth of 288.0 GB/s edges out the N1 20SM's 273.2 GB/s despite the NVIDIA chip's wider 256-bit bus. Its 2048 shading units, while fewer than the NVIDIA part's 2560, are paired with higher clocks: 2695 MHz boost versus 2346 MHz boost. The RX 7650 GRE also has full API support with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1 20SM lists N/A for all three. The AMD card has a measured benchmark presence at the 83rd percentile with an average score of 42723, making it the only one of the two with verified performance data.

The NVIDIA N1 20SM wins in raw resource counts and memory capacity. It has 2560 shading units versus 2048, 160 TMUs versus 128, and 80 tensor cores versus none. Its 128 GB LPDDR5X memory dwarfs the AMD card's 8 GB, and its 256-bit bus is twice as wide. Its texture rate of 375.4 GTexel/s exceeds the AMD card's 345.0 GTexel/s. It uses a 5 nm process versus 6 nm, runs on PCIe 5.0 x16 versus PCIe 4.0 x8, and draws no external power connectors as an integrated part. The 382 mm² die is larger than the 204 mm² AMD die, though the transistor count for the NVIDIA chip is unknown. The N1 20SM also has a later release date in the database.

The specification table highlights a fundamental mismatch in design philosophy. The RX 7650 GRE is a conventional discrete graphics card with high clocks, high fill rates, and a compact 204 mm² die. The N1 20SM is an integrated processor with a larger die, more memory, more shaders, and tensor cores, but lower clocks and dramatically lower pixel throughput. The 741 MHz base clock on the NVIDIA part is less than half the AMD card's 1720 MHz base clock. The 24 ROPs on the N1 20SM are the most severe limitation, capping its fill rate at 56.30 GPixel/s. The RX 7650 GRE's 64 ROPs, combined with its higher clocks, give it a 172.5 GPixel/s pixel rate that is more than three times higher. For any workload that stresses rasterization output, the AMD card is the clear winner on paper. For memory capacity and tensor operations, the NVIDIA part holds the advantage.
