Skynet Ran at 60 Teraflops. That Is One Gaming GPU Now.
31 Oct 2026
In Terminator 3 (2003), Skynet runs at "60 teraflops per second", which beat the fastest computer on Earth at the time. In 2026 that is one RTX 4090, or 1/18,000th of a GB300 NVL72 rack at FP4. Count in FP64, the precision a 2003 supercomputer meant, and the whole rack is only 1.7 Skynets. A Halloween look at why a TFLOPS figure without a precision is a plot device, not a spec.

Dense vs Sparse TFLOPS: How to Read a 2:4 Sparsity Figure
11 Oct 2026
Structured 2:4 sparsity doubles a tensor-core TFLOPS figure on paper. Where the 2x comes from, when it applies, and which number to compare.

The hardware and the clouds that landed here most recently.
New hardware
One Database. Every Precision.
Vendor datasheets use different formats, units, and conditions. We normalize everything so you can compare what actually matters.
Normalized Across Vendors
NVIDIA, AMD, Intel, Google, and more — all converted to the same TFLOPS baseline at every precision level. No more cross-referencing datasheets.
Every Precision Tracked
FP64 through FP4, including BF16, TF32, and INT8. Filter and sort by the precision your workload actually uses — not just the headline number.
Specs Tied to Sources
Every data point links back to its origin: official datasheets, vendor whitepapers, or verified benchmarks. No unattributed claims.
