AMD Radeon RX 7650 GRE vs NVIDIA H100 CNX Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the AMD Radeon RX 7650 GRE and the NVIDIA H100 CNX. The head-to-head benchmark array is empty, and neither product has a shared test result in the database. The AMD Radeon RX 7650 GRE has two recorded benchmarks: a 3DMark Steel Nomad DX12 score of 2336 and a Geekbench OpenCL score of 83109. The NVIDIA H100 CNX has no recorded benchmarks at all, contributing to its average benchmark score of 0 and a 50th percentile ranking among all GPUs.

The AMD Radeon RX 7650 GRE holds an 83rd percentile ranking across all GPUs, with an average benchmark score of 42723. Its nearest rivals in the database include the NVIDIA GeForce RTX 4070 SUPER (average score 43223, delta of -1.2%), the NVIDIA Quadro M6000 24 GB (average score 43262, delta of -1.2%), the NVIDIA GeForce RTX 5050 Mobile (average score 43268, delta of -1.3%), and the NVIDIA Quadro M6000 (average score 43301, delta of -1.3%). These deltas indicate the AMD card trails each of these rivals by roughly 1.2% to 1.3% in average benchmark score.

Because the H100 CNX lacks any benchmark entries, no direct comparison of scores, deltas, or percentile shifts can be derived from the database. The data shows that the AMD part is actively benchmarked and ranked, while the NVIDIA part is not. This absence means any quantitative head-to-head comparison is impossible from recorded measurements alone.

The Geekbench OpenCL score of 83109 for the AMD card reflects compute performance in an OpenCL workload, while the 3DMark Steel Nomad DX12 score of 2336 reflects rasterized gaming performance under DirectX 12. The H100 CNX has no equivalent recorded scores, so its relative standing in either workload cannot be quantified. The database records zero wins for either product in head-to-head comparisons, which is consistent with the empty benchmark array.

Where Each One Wins

The AMD Radeon RX 7650 GRE demonstrates clear strengths in consumer-facing workloads. Its 3DMark Steel Nomad DX12 score of 2336 and Geekbench OpenCL score of 83109 indicate functional capability in both gaming and general-purpose compute. The card delivers 22.08 TFLOPS of FP32 performance and 22.08 TFLOPS of FP16 performance at a 1:1 ratio, making it suitable for workloads where single-precision and half-precision throughput are equally important. Its pixel rate of 172.5 GPixel/s and texture rate of 345.0 GTexel/s support high-resolution rasterization tasks.

The NVIDIA H100 CNX, while lacking recorded benchmarks, presents a different profile in its specifications. It delivers 53.84 TFLOPS of FP32 performance, more than double the AMD card's FP32 throughput. Its FP16 performance reaches 215.4 TFLOPS at a 4:1 ratio, which is nearly ten times the AMD card's FP16 output. The H100 CNX also carries 456 tensor cores, which the AMD card does not have at all, indicating a specialization in matrix operations and AI acceleration. Its memory subsystem, with 80 GB of HBM2e on a 5120-bit bus, provides 2.04 TB/s of bandwidth, vastly exceeding the AMD card's 288.0 GB/s.

Based on the recorded specifications, the AMD card wins in scenarios requiring standard graphics output, DirectX 12 Ultimate support, and lower power consumption. The NVIDIA card wins in raw compute throughput, memory capacity, and memory bandwidth, but its lack of display outputs means it cannot drive monitors directly. The AMD card supports HDMI 2.1a and DisplayPort 2.1 outputs, while the H100 CNX has no outputs, making the AMD part the only one capable of rendering to a screen.

The H100 CNX's 456 tensor cores and 215.4 TFLOPS of FP16 performance point toward deep learning inference and training tasks. The AMD card's 32 ray tracing cores and 2048 shading units support real-time ray tracing in gaming workloads. The database shows the AMD card is ranked at the 83rd percentile among all GPUs, while the H100 CNX sits at the 50th percentile, but this ranking is based on benchmark participation, not actual scores, since the NVIDIA part has no recorded benchmarks.

The Verdict

The data indicates that the AMD Radeon RX 7650 GRE and the NVIDIA H100 CNX serve entirely different purposes, and the recorded measurements reflect this divergence. The AMD card has active benchmark results, a 83rd percentile ranking, and a 42723 average benchmark score. Its nearest rivals all sit within 1.3% of its average score, showing that it competes in a tight performance band among consumer and workstation GPUs. The NVIDIA card has no recorded benchmarks, a 50th percentile ranking, and a zero average score, which means its database profile is built entirely from specifications rather than measured performance.

For users selecting based on recorded benchmark data, the AMD card is the only one with evidence of performance. Its 3DMark Steel Nomad DX12 score of 2336 and Geekbench OpenCL score of 83109 demonstrate measurable capability in both gaming and compute workloads. The card's 22.08 TFLOPS of FP32 and FP16 performance, combined with 32 ray tracing cores and support for DirectX 12 Ultimate, position it for real-time graphics and consumer applications.

The NVIDIA H100 CNX, despite lacking benchmarks, shows specifications that target a different workload class. Its 53.84 TFLOPS of FP32, 215.4 TFLOPS of FP16, 456 tensor cores, and 80 GB of HBM2e memory with 2.04 TB/s of bandwidth indicate a design for high-throughput compute, particularly in areas involving matrix operations and large datasets. The absence of display outputs and API support records confirms that it is not intended for direct rendering.

The database shows the AMD card at the 83rd percentile and the NVIDIA card at the 50th percentile, but this ranking gap stems from the NVIDIA card's lack of benchmark participation rather than a measured performance deficit. The AMD card's 2048 shading units and 64 render output units provide a pixel rate of 172.5 GPixel/s, while the NVIDIA card's 14592 shading units and 24 render output units yield a lower pixel rate of 44.28 GPixel/s, suggesting the NVIDIA part is not optimized for fill-rate-bound workloads.

Selection between these two products depends on the workload profile. The AMD Radeon RX 7650 GRE is the appropriate choice for systems requiring display output, DirectX 12 Ultimate support, and lower power draw at 170 W. The NVIDIA H100 CNX is suited for compute environments where FP16 throughput, tensor core operation, and memory bandwidth are priorities, accepting a 350 W power draw and no display capability. The recorded data confirms that these are complementary rather than competing products.
