Intel Core i7-2600K PC: system figures

provisional A figure marked provisional is recorded but not accepted: its evidence is unsettled. It may rely on one source, an unconfirmed announcement, or a digit read from a damaged scan. The reason appears under the figure. The catalog shows the figure but never uses it in a multiplier. How records are judged.

Metric Value Evidence Basis Method Source
Memory capacity whole-system provisional 8 GiB Confirmed Vendor-rated Design capacity Stated by the vendor This figure remains provisional until the cited source is corroborated for the exact configuration.

Clock frequency gpu provisional unknown Intel states a frequency for each generation and the generations disagree: Intel HD Graphics 3000 on the Core i7-2600K is specified at 850 MHz base and 1.35 GHz maximum dynamic, UHD Graphics 770 on the Core i9-14900K at 300 MHz base and 1.65 GHz maximum dynamic. Both figures are vendor statements and neither can stand for the other. Not stated Vendor-rated Nominal clock Stated by the vendor This is a documented absence rather than an unexamined one. Two vendor specification records were read for the machines fitted with this component, and they answer the question differently in both directions: the older part has the higher base clock and the lower ceiling. What is missing is not a document but a component: the entry would need splitting into the named graphics devices, and the Core 2 Duo platform's chipset graphics is a third device the processor's own name does not identify.
Peak FP32 rate gpu provisional unknown Intel's specification record for the newest of these graphics devices states an execution-unit count of 32 and no floating-point rate at any precision. An execution-unit count is not a rate: converting one to the other needs a published figure for floating-point operations per unit per clock, which the specification does not give. Not stated Vendor-rated Theoretical peak Stated by the vendor A documented absence. The vendor record was read and states the unit count without the per-unit throughput that would turn it into a rate, and the component in any case spans graphics generations with different clocks, so one answer could not describe them even if the throughput were published.

Memory bandwidth memory provisional unknown One of the three machines fitted with this component can be documented and the component cannot: Intel rates the Core i7-2600K's dual-channel DDR3-1333 interface at 21 GB/s. The same component also stands for the Pentium 4's DDR and the Core 2 Duo E6600's DDR2, which are different standards at different transfer rates, so the one figure available describes a third of the component. Not stated Vendor-rated Theoretical peak Stated by the vendor A documented absence, and a demonstration of what would fix it. A vendor rating exists for one member; recording it here would silently give the Pentium 4 and Core 2 Duo platforms a DDR3 bandwidth. The entry needs splitting per memory generation before any of the three can be answered.

Editorial notes

This entry has no photograph, and that is a decision rather than a gap: it describes a processor in a typical machine of its era rather than a model anybody sold, so there is no object to photograph. A picture of some particular case would attach a claim about that computer to a record which deliberately makes none.
