65W Non-X AMD Ryzen 7 7700 and Ryzen 5 7600 Surface

[btarunr]

The SiSoft SANDRA user database has just been pinged by two new unreleased AMD Ryzen 7000 series "Zen 4" processor models, the Ryzen 7 7700 and Ryzen 5 7600. These chips have the same 8-core/16-thread and 6-core/12-thread core-counts as the 7700X and 7600X, respectively; but with lower clock speeds, and more importantly, a lower TDP of just 65 W. This would put their package power tracking (PPT) limit around 90 W, down from the 105 W and 140 W of the their "X" siblings.

The 7600 and 7700 come with a base frequency of 3.80 GHz, as detected by SANDRA. Every other specification, such as cache size, is the unchanged from the 7600X or 7700X. There's no word on the availability, but it's likely that AMD would debut these chips in the OEM channel first, especially given that the 7600 has the potential to undercut sales of the embattled 7600X. Things could get interesting as Intel debuts the lower end of its 13th Gen Core i5 series, which are rumored to be based on the "Alder Lake" microarchitecture, and 6P+4E SKUs.

The 7700X works great when limited to 65 W TDP (88W PPT), so I think this pair is a welcome addition.

Can't wait for them to make an APU out of these.

Without disagreeing with your statement, I think it is important to point out that all APUs so far are monolithic dice, with IO, CCX, and iGPU all on the same die. This will reduce power consumption by ~20w for the IF alone, and should drastically improve thermals. I think it is almost certain that the Zen 4 APUs will follow this trend.

The 7600 non-X could (and should) find it's way into the retail market soon.

... but with lower clock speeds, and more importantly, a lower TDP of just 65 W.

Makes me wonder why that was necessary, and if you could overclock it.

You can also run a 7600X or 7700X with a lower PBO setting at 65W, so would be interesting to see how big the speed difference will be at 65W (if any).

If I had to guess, it's the CCDs that can't quite make full boost clock at stock, so they turn on ECO mode by default. Will be home interesting to see the CB scores vs the X models.

They've also had castrated cache and pci lanes

The i5 13400 / 13400F is based on Alder Lake architecture but not the i7 13700 / 13700F. Paired with a B760 board those will probably be the go-to builds for most gamers.

Generally due to being laptop chips repurposed for the desktop market. Hopefully that is not the case this time around, we will see.
