GPU Comparison

The benchmark data places the AMD Radeon RX 7650 GRE and NVIDIA RTX A6000 in a statistical tie by average score, yet their performance profiles are radically different. The RX 7650 GRE posts an average benchmark score of 42,723, while the RTX A6000 sits at 42,653, a negligible 0.2% difference in favor of the AMD card. Both GPUs occupy the 84th percentile among all GPUs, meaning they are positioned at the same overall performance tier. However, this aggregate parity masks a stark divergence in workload-specific capability, with the RTX A6000 dominating the only direct head-to-head benchmark available while the RX 7650 GRE counters with vastly higher efficiency per watt.

Head-to-Head Benchmarks

The sole direct comparison in the data is the Geekbench OpenCL test, and the result is lopsided. The NVIDIA RTX A6000 scores 180,149, while the AMD Radeon RX 7650 GRE manages 83,109. This represents a 53.9% deficit for the AMD card, marking a decisive win for NVIDIA in this compute-oriented workload. The RTX A6000’s score is more than double that of the RX 7650 GRE, indicating a fundamental advantage in raw compute throughput that the AMD card cannot overcome in this test.

The deltaPct values in the nearestRivals data reinforce the idea that these two cards are closely matched on average, but the Geekbench OpenCL result shows how misleading averages can be. In that specific test, the A6000 is not just ahead—it is in a different performance class. The RX 7650 GRE’s 83,109 score is a mid-range result, while the A6000’s 180,149 places it in workstation-tier territory. For any application that relies heavily on OpenCL compute, the NVIDIA card is the clear choice based on this data.

Conversely, the RX 7650 GRE does not have a listed head-to-head win in the provided benchmarks. Its average score edge of 0.2% over the RTX A6000 comes from a broader benchmark suite, but in the one direct comparison available, it loses decisively. This suggests that the AMD card’s strength lies in other, unlisted tests that contribute to its slightly higher aggregate score, rather than in the OpenCL workload where NVIDIA’s architecture excels.

Architecture Differences

The architectural divide between these two GPUs is substantial, starting with the manufacturing process. The AMD Radeon RX 7650 GRE uses a 6 nm TSMC node, while the NVIDIA RTX A6000 relies on an 8 nm Samsung process. This gives AMD a density advantage: the RX 7650 GRE packs 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The RTX A6000, by contrast, has 28,300 million transistors spread across a massive 628 mm² die, for a density of 45.1 million per square millimeter. AMD’s smaller node allows for a much more compact chip, though NVIDIA uses its larger die to deliver significantly more raw resources.

Core counts tell a story of scale versus efficiency. The RTX A6000 features 10,752 shading units, 336 texture mapping units, and 112 ROPs, dwarfing the RX 7650 GRE’s 2,048 shading units, 128 TMUs, and 64 ROPs. NVIDIA also includes 84 RT cores and 336 tensor cores, while AMD offers 32 RT cores and no tensor cores at all. This is a 5.25x difference in shading units and a 2.6x difference in TMUs, explaining the A6000’s massive lead in raw compute rates: 38.71 TFLOPS FP32 versus 22.08 TFLOPS for the AMD card, and 604.8 GTexel/s versus 345.0 GTexel/s.

Memory configurations are equally divergent. The RTX A6000 comes with 48 GB of GDDR6 on a 384-bit bus, delivering 768.0 GB/s of bandwidth. The RX 7650 GRE has 8 GB of GDDR6 on a 128-bit bus, for 288.0 GB/s. That is a 6x difference in capacity and a 2.67x difference in bandwidth. NVIDIA’s card is clearly built for data-intensive workloads, while AMD’s is oriented toward mainstream gaming and lighter compute tasks.

Clock speeds reverse the trend. The RX 7650 GRE boosts to 2695 MHz with a base of 1720 MHz and a game clock of 2350 MHz, while the RTX A6000 boosts to just 1800 MHz with a 1410 MHz base. AMD’s higher clocks partially compensate for its lower core count, but not enough to close the compute gap. The RX 7650 GRE also has a higher memory clock at 2250 MHz (18 Gbps effective) versus 2000 MHz (16 Gbps effective), though the A6000’s wider bus makes that irrelevant for bandwidth.

The Verdict

The data points to the NVIDIA RTX A6000 as the superior compute performer, with a 53.9% lead in Geekbench OpenCL and more than 1.75x the FP32 throughput, but the AMD Radeon RX 7650 GRE delivers comparable overall scores with far lower power draw and a much smaller die. The RTX A6000 is an end-of-life workstation card with 48 GB of memory, 336 tensor cores, and a 768.0 GB/s bandwidth, built for professional workloads. The RX 7650 GRE is an active mainstream card with 8 GB and no tensor cores, but it achieves near-identical average benchmark scores at 165 W versus the A6000’s 300 W.

For users prioritizing raw compute, memory capacity, or AI features, the RTX A6000 is the clear winner based on the data—its 180,149 OpenCL score and 38.71 TFLOPS FP32 are unmatched by the AMD card. However, the RX 7650 GRE’s higher clocks, smaller process node, and dramatically lower power requirements make it a more efficient choice for gaming and lighter workloads. The average score tie suggests that in real-world mixed usage, the two cards trade blows, but the A6000’s specialization in compute cannot be ignored.

Where Each One Wins

NVIDIA RTX A6000 wins in: OpenCL compute workloads, where it scores 180,149 versus 83,109 for the AMD card. It also wins in any scenario requiring more than 8 GB of memory, given its 48 GB capacity, and in AI or machine learning tasks thanks to its 336 tensor cores. Its 768.0 GB/s bandwidth and 38.71 TFLOPS FP32 performance make it the choice for professional rendering, simulation, and data science.

AMD Radeon RX 7650 GRE wins in: Power efficiency, with a 165 W TDP versus the A6000’s 300 W, and in raw clock speed, with a 2695 MHz boost versus 1800 MHz. Its smaller 6 nm die and lower 450 W suggested PSU make it easier to integrate into mainstream systems. It also wins on average benchmark score by a hair, 42,723 versus 42,653, suggesting it holds its own in gaming and mixed workloads despite its hardware limitations.
