Accelerator
AMD Radeon RX 7900 XTX: 24 GiB of GDDR6, 960 GB/s peak bandwidth, and 61.42 TFLOP/s FP32.
A Sapphire Radeon RX 7900 XTX, a partner card built to AMD's reference specification.
AMD calls 2300 MHz the game clock and 2500 MHz the boost clock. The 61.42 TFLOPS peak is tied to the boost clock; it must not be recalculated from the game clock and silently relabeled as the same rate.

| Clock frequency gpu | 2300 MHz | Confirmed | Vendor-rated | Nominal clock Stated by the vendor The lower declared clock. The separately named upper clock is a different quantity and uses peak-clock. | |
| Clock frequency gpu | 2500 MHz | Confirmed | Vendor-rated | Peak clock Stated by the vendor AMD calls this the boost clock. Its separate game clock is a nominal-clock measurement. | |
| Peak FP32 rate gpu | 61.42 TFLOP/s | Confirmed | Theoretical | Theoretical peak Stated by the vendor 12,288 stream processors × 2 FP32 operations per cycle × 2500 MHz boost clock. AMD’s 61.42 TFLOPS uses 12,288 stream processors × two FP32 operations per cycle × the 2500 MHz boost clock, never the 2300 MHz game clock. | |
| Geekbench Compute score, opencl gpu | 208 566 | Confirmed | Measured | Benchmark chart average Published independently geekbench-compute 7 , opencl A dated capture of the benchmark publisher’s rolling average for this graphics processor, read from the 25 July 2026 OpenCL chart. Version 7 calibrates a compute result against a baseline of 100,000, so it may be compared only with another Geekbench 7 OpenCL figure from this curation round, never with a Metal figure, an earlier version or a processor score. The chart also lists this processor under “Radeon RX 7900 XTX”, at 212 610; the row naming the product as its maker does was taken, and the disagreement is recorded in the conflict ledger. | |

| Memory bandwidth memory | 960 GB/s | Confirmed | Theoretical | Theoretical peak Stated by the vendor Vendor-stated maximum transfer rate of this memory interface, not a benchmarked application result. | |

a + b + … sum v1 Adds 1 memory-bandwidth figure obtained by theoretical-peak. Nothing in the catalog is left out of it. A total is only as trustworthy as the decision about what belongs in it, so both the terms and the exclusions are named records.
This accelerator’s whole-system memory is its fitted frame buffer; host memory is excluded. Partner cards may differ from this reference configuration.
