Guys as most of you know AMD will release a new driver real soon, this one coming with Mantle support. I just heard that the driver is delayed a bit more so it likely won't be today. However we are allowed to share some stuff with you guys. The upcoming 14.1 Beta driver will receive many improvements. Two important ones though, read more after the break.
Frame pacing (Frame latency)
The first being that AMD Catalyst 14.1 is the ?phase 2? frame pacing driver they announced in October of last year. It enables frame pacing support in DX10 and DX11 applications on resolutions higher than 1600p with products that don?t feature AMDs XDMA technology. Example products include the HD 7000 Series, or the R9 280X and R9 270X GPU. This driver also helps improve the frame pacing in AMD Dual Graphics configurations, such as the new ?Kaveri? APU paired with an AMD Radeon R7 250 GPU! We encourage you and your readers to test our initial implementation, and provide feedback as you?re able.
HSA
The upcoming catalyst driver is also AMD?s first HSA-enabled graphics driver, which allows the GPU and CPU silicon of the new ?Kaveri? APU to intelligently cooperate for improved performance. Supporting applications for testing include Libre Office v4.2.0.1+ and Corel AfterShot Pro v1.2.0.6+, with many more to come soon

Mantle ready
Obviously AMD will launch the driver with Mantle support, DICE will rool out an update today that should allow Mantle compatibility.
Here's the thing, you've been seeing a lot of speculation (intentionally spread by AMD) with 40% performance gains. That is both true and not. For high-end systems with fast CPUs it's not, you will definitely see gains in performandce. But Mantle helps where the CPU is limited, and that is great news for slower CPU products like say Kaveri. Mantle is an incredibly powerful tool for alleviating CPU bottlenecks--such as API overhead or inefficient multi-threading--so systems with entry-level, mid-range, or otherwise modestly-priced processors stand to see the biggest gain.
Here are some initial numbers as delivered by AMD:
Battlefield 4(EA-DICE)
CPU-limited scenario: 40.9% (1080p) and 40.1% (1600p) performance improvement under Ultra settings and 4xAA on the AMD A10-7700K with an AMD Radeon? R9 290X.
GPU-limited scenario: 2.7% (1080p) and 1.4% (1600p) performance improvement under Ultra settings and FXAA on the Core i7-4960X with an AMD Radeon? R7 260X
Average uplift for 1080p: 13.28% (Average of 290X and 260X data on the i7-4960X, A10-7700K, FX 8350 and i5-4670K)
Average uplift for 1600p: 11.35% (Average of 290X and 260X data on the i7-4960X, A10-7700K, FX 8350 and i5-4670K)
In reality you'll be GPU limited extremely fast, everybody with say a mid-range GPU and normal processor is GPU limited. However of you have a more low-end setup, that's gonna kick ass in extra performance. All of the sudden APUs make much more sense, if the software supports Mantle of course. That's all I can share right now.
