Architecture Differences

The AMD Radeon RX 7650 GRE is built on the Navi 33 chip using RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi III (RX 7000) generation. It uses a 6 nm process at TSMC with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M / mm². The Intel Arc B580 uses the BMG-G21 chip with Xe2-HPG architecture, belongs to the Battlemage (Arc 5) generation, and is fabricated on a 5 nm process at TSMC with 19,600 million transistors on a 272 mm² die, giving a density of 72.1M / mm².

The shader configurations differ notably. The AMD card has 2048 shading units, 128 texture mapping units, 64 raster output units, and 32 ray tracing cores. The Intel card has 2560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores. Despite fewer shading units and TMUs, the AMD card delivers higher raw FP32 throughput at 22.08 TFLOPS, while the Intel card manages 13.67 TFLOPS FP32. In FP16 compute, the AMD card offers 22.08 TFLOPS at a 1:1 ratio, whereas the Intel card provides 27.34 TFLOPS at a 2:1 ratio.

Clock behavior also diverges. The AMD card has a base clock of 1720 MHz, a game clock of 2350 MHz, and a boost clock of 2695 MHz. The Intel card runs a fixed 2670 MHz for both base and boost, with no separate game clock listed. Memory clocks see the Intel card at 2375 MHz (19 Gbps effective) versus 2250 MHz (18 Gbps effective) for the AMD card.

The two cards share the same PCIe 4.0 x8 bus interface, dual-slot form factor, 1x 8-pin power connector, 450 W suggested PSU, and identical display outputs (1x HDMI 2.1a, 3x DisplayPort 2.1). Both are listed as Active in production status. The AMD card was released on 2025-02-06, while the Intel card launched earlier on 2024-12-12. The AMD card's predecessor is Navi II and its successor is Navi IV; the Intel card's predecessor is Alchemist with no successor listed.

Head-to-Head Benchmarks

The database records two direct head-to-head comparisons between these cards, and the Intel Arc B580 wins both.

In 3DMark Steel Nomad DX12, the Intel Arc B580 scores 3068 against the AMD Radeon RX 7650 GRE's 2336. The delta of -23.9% indicates the AMD card trails by nearly a quarter in this modern DirectX 12 workload. This is a substantial margin that places the two cards in different performance tiers for this test, despite the AMD card's higher overall average benchmark score across all recorded tests.

In Geekbench OpenCL, the Intel Arc B580 scores 92821 against the AMD card's 83109. The delta is -10.5%, meaning the AMD card is about a tenth behind in this compute-oriented workload. While the gap is smaller than in Steel Nomad, it still represents a clear win for the Intel architecture in general-purpose GPU compute.

The overall benchmark totals reflect a broader divergence. The AMD card's average benchmark score of 42723 is significantly higher than the Intel card's 23021, and the AMD card sits in the 83rd percentile of all GPUs versus the 68th percentile for the Intel card. This discrepancy between the head-to-head results and the average scores suggests the AMD card performs relatively better in the wider set of benchmarks that feed the average, while the Intel card excels specifically in the two directly compared tests.

The nearest rival data reinforces this split. The AMD card's closest competitors, the NVIDIA GeForce RTX 4070 SUPER at 43223 and the NVIDIA Quadro M6000 24 GB at 43262, sit within 1.2% of its average score. The Intel card's closest rivals, the AMD Radeon RX 580 2048SP at 23061 and the NVIDIA GeForce RTX 3080 at 23172, are within 0.7% of its average. These clusters show that the AMD card competes in a higher average performance bracket, while the Intel card sits in a lower one, even though the Intel card wins the specific head-to-head tests recorded.

Specification Differences

The two cards differ across nearly every core specification. The AMD Radeon RX 7650 GRE uses the Navi 33 chip with RDNA 3.0 architecture, while the Intel Arc B580 uses the BMG-G21 chip with Xe2-HPG architecture. Process nodes differ at 6 nm versus 5 nm, and transistor counts differ at 13,300 million versus 19,600 million. Die size is 204 mm² for AMD and 272 mm² for Intel, with transistor densities of 65.2M / mm² and 72.1M / mm² respectively.

Memory specifications show the Intel card with a clear capacity and bandwidth advantage: 12 GB versus 8 GB, 192-bit versus 128-bit bus, and 456.0 GB/s versus 288.0 GB/s bandwidth. Memory clock is also higher on the Intel card at 2375 MHz versus 2250 MHz.

Compute resources differ in both directions. The Intel card has more shading units (2560 vs 2048), more TMUs (160 vs 128), and more ROPs (80 vs 64). The AMD card has more ray tracing cores (32 vs 20). FP32 throughput favors AMD at 22.08 TFLOPS versus 13.67 TFLOPS, while FP16 throughput favors Intel at 27.34 TFLOPS versus 22.08 TFLOPS, with different ratios (1:1 for AMD, 2:1 for Intel).

Clock speeds show the AMD card with a lower base clock of 1720 MHz but a higher boost clock of 2695 MHz, plus a listed game clock of 2350 MHz. The Intel card runs at a flat 2670 MHz for both base and boost with no game clock listed. TDP differs at 170 W for AMD and 190 W for Intel.

Physical dimensions differ in length: the AMD card measures 204 mm (8 inches), while the Intel card measures 272 mm (10.7 inches). Both are 115 mm (4.5 inches) tall, and only the Intel card has a listed width of 45 mm (1.8 inches). Release dates differ by roughly two months, with Intel launching on 2024-12-12 and AMD on 2025-02-06. The launch MSRP differs by 30 USD, with AMD at 279 USD and Intel at 249 USD.

Where Each One Wins

The Intel Arc B580 wins in the two recorded head-to-head benchmarks. The 3DMark Steel Nomad DX12 result shows a 23.9% advantage, making it the stronger choice for that specific DirectX 12 workload. The Geekbench OpenCL result shows a 10.5% advantage, indicating solid general compute performance. The Intel card also offers a larger memory pool at 12 GB with 456.0 GB/s bandwidth, which supports workloads that exceed the 8 GB capacity of the AMD card.

The AMD Radeon RX 7650 GRE wins in overall average benchmark score, 42723 versus 23021, and in percentile ranking, 83rd versus 68th. Its nearest rivals sit at much higher average scores, indicating the AMD card occupies a higher performance tier when measured across the full benchmark suite. The AMD card also delivers higher FP32 throughput at 22.08 TFLOPS versus 13.67 TFLOPS, more ray tracing cores at 32 versus 20, and a lower TDP at 170 W versus 190 W.

The use-case split follows the data. For applications that stress raw FP32 compute and ray tracing, the AMD card's specifications suggest an advantage. For applications that need large memory capacity, high memory bandwidth, or the specific workload patterns in Steel Nomad and OpenCL tests, the Intel card shows the edge. The Intel card's higher FP16 throughput at 27.34 TFLOPS also favors workloads that can use packed math, though the 2:1 ratio indicates it trades FP32 throughput for that capability.

The benchmark results indicate that the Intel Arc B580 performs better in the direct comparisons available, while the AMD Radeon RX 7650 GRE performs better in the broader benchmark database average. Buyers and system builders should weigh the specific tests and workloads that matter most, since the two cards lead in different measurement contexts.
