Except that the DDR3 7750 has DDR3-1600 memory- Kaveri should use at least 2133MHz, hopefully 2400MHz. That will help alleviate the bandwidth bottleneck a little.
That's actually a lot, going from 25.6 GB/s to 38.4 GB/s. As bandwidth is the restriction here, I would expect to see this easily beat the 7750 with DDR3 1600 MHz. With DDR3 2400 MHz this will be the most balanced APU, graphically, that AMD has released by far. I'm expecting good things from power consumption.
I was gonna say, isn't that an issue with AMD's current memory controller? While DDR3-2133 may provide a significant amount of bandwidth over DDR3-1600, AMD's memory controller isn't efficient enough to effectively use all of it; something Intel doesn't have as much of a problem with.
Isn't it scheduled for a redesign come Excavator?
Here's a neat idea... AMD should come up with a PCIe16 "daughter card" option for its APU series. Instead of sharing DDR3 system RAM, one can purchase a daughter-card to plug into the PCIe16 slot. It doesn't have a separate GPU on it, only extensions for the APU to improve it, and/or 1-2GB of dedicated GDDR5 memory.
...perhaps not the most cost-effective... but a fun thought, at least.

funny, because it is exact opposite of what they want to do (Unified memory)

Neat idea, but wouldn't that far exceed the bandwidth that a PCI-E 16x slot would allow?
PCIe 3.0's 8 GT/s bit rate effectively delivers 985 MB/s per lane
1920x1080, medium+SSAO settings and ~30fps average is quite good. We'd need to see how 7750 performs in single player campaign mode.pcper hand-on[more off than on]

Memory in the system was running at 2133 MHz.

Correct me if I am wrong, but I think this slide hints that AMD is no longer interested in making more traditional "Big Cores".
I think FX-8350 will be the last AMD processor with the "Big cores" :'''(, from now on it will be HSA.
More GPU cores and less CPU cores.....??

That article has one problem
Both SR and Excavator ARE big cores. They are not "small" core family. So, no , AMD is still doing the big cores. They are not doing the more cores approach on desktop though.
They opted to boost the IPC and eliminate bottlenecks. Who cares if Excavator will be 2M/4?TD) in 2015 IF it would to perform like 4M/8T 8350+? I wouldn't certainly care, it would be even better marketing-wise . Excavator core seems to be going after just that, building up the individual core strength in order to roughly match up with Haswell/Broadwell generation. I say roughly since it's really hard to do it via only IPC, AMD will opt for also high clock design and some HSA features. But if Ex. core comes at ~90% of Haswell's IPC , or roughly at IB+ territory, it won't mater if Skylake will be +10 or so % more than Haswell, or if it will support AVX3 (I doubt even AVX2 will be supported and give benefit in mainstream software by that time). It won't matter since both will be so fast nobody would care about 10 or 20% difference. They would care about feature set, price and iGPU performance(what the chip can do in their workloads).
