The Tech Report writes some extra details about AMD's upcoming Kaveri APU were revealed by a newly leaked slide. It highlights that Kaveri will have a PCI Express interface dedicated to SSDs, but there's no word on the number of lanes or whether it's Gen3. Kaveri is anticipated to be launched on January 14, 2014.
We already know a couple of things about Kaveri's CPU and GPU components. The CPU will have up to four Steamroller cores, and the Radeon will sport as many as eight GCN compute units. AMD hasn't revealed the number of shader processors in each of those GCN units, though, and it hasn't discussed clock speeds. The slide makes a couple of performance claims, though. The CPU cores are said to deliver a 20% performance boost over the Piledriver cores in existing Richland chips. Kaveri's integrated Radeon is supposed to be 30% faster than its Richland counterpart, as well.
The slide appears to pertain to mobile platforms, and it includes some information on TDP ratings and expected battery life. If those details are accurate, Kaveri APUs will be available with 15-35W thermal envelopes. The slide indicates that AMD is "targeting" 11 hours of MobileMark 2007 run time with a 62Wh battery. That's a "pre-silicon projection and not based on actual measured data," the accompanying footnote adds.
