Slowly but surely, AMD is planning to flesh out its second generation Ryzen processor family, both on the desktop and in mobile. There have been numerous leaks that reveal as much. The latest leak centers on a couple of low power processors that are joining the Ryzen family, including the Ryzen 7 2700E and Ryzen 5 2600E.
These two upcoming desktop parts both have a 45W TDP, compared to 95W and 105W for their full power counterparts. They will compete with Intel's Core "T" series, which are 35W parts that can be configured down to 25W.
As for the specs, the Ryzen 7 2700E and Ryzen 5 2600E are similar to the Ryzen 7 2700X and Ryzen 5 2600X, just with lower clockspeeds (and of course a low power profile). Here is how they compare:
- Ryzen 7 2700X: 8 cores / 16 threads, 3.7GHz to 3.7GHz, 20MB L2+L3 cache, 105W TPD
- Ryzen 7 2700E: 8 cores / 16 threads, 2.8GHz base clock, 20MB L2+L3 cache 45W TDP
- Ryzen 5 2600X: 6 cores / 12 threads, 3.6GHz to 4.2GHz, 19MB L2+L3 cache, 95W TDP
- Ryzen 5 2600E: 6 cores / 12 threads, 3.1GHz base clock, 19MB L2+L3 cache, 45W TDP
The low power SKUs have the same number of cores and threads, and the same amount of L2 and L3 cache. They have significantly lower base clocks, which helps lower the TDP, and presumably lower boost clocks, though that information has not been leaked (yet).
One thing that's interesting is that the Ryzen 7 2700E's base clock is 900MHz slower than its Ryzen 7 2700X counterpart, while the Ryzen 5 2600E's base clock is 'only' 500MHz slower than its Ryzen 5 2600X counterpart. There's a bigger gap in the higher end processors because there are more cores underneath the hood. Keeping the TDP at 45W requires a more aggressive downclock with 8 cores and 16 threads.
Depending on where the boost clocks fall, these could be intriguing options, both for users with lower power needs and anyone wanting a current generation processor that runs a bit cooler than the mainstream lineup.
