Memory
Eight gibibytes of GDDR5 shared by the processor and the graphics units. The three PlayStations before it split their memory in two.
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 bandwidth memory provisional | 176 GB/s | Confirmed | Vendor-rated | Theoretical peak Stated by the vendor, before the hardware shipped Bandwidth of the unified GDDR5 memory, per the introduction of February 2013. Stated nine months before the console shipped and not repeated by the launch release. It is also one figure where two earlier records would have needed two: processor and graphics traffic share this bus rather than owning separate ones. | |
| Memory capacity whole-system | 8 GiB | Confirmed | Vendor-rated | Design capacity Stated by the vendor Unified system memory, shared by the eight processor cores and the 18 compute units. Both releases write "8GB", meaning 8 GiB. Recorded at whole-system scope rather than memory scope because it is the machine's memory: unlike the earlier PlayStations, there is no second pool this figure excludes. |
176 000 000 000 B/s
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 is the first console record in the catalog whose memory capacity is a single honest number. The PlayStation, PlayStation 2 and PlayStation 3 each keep a processor pool and a graphics pool that cannot be spent on each other's work, so adding them describes memory the machine does not have. Here the pools are the same memory, and the sum is the machine.
