Thanks for the feedback Merlion. I’m going to provide this information to the corresponding department.
Regarding your questions, I’m going to try to get that information for you.
I’ll keep you posted.
Thank you, Sylvia. I'm also searching the answer.
About question 1, I find that the same 5200 GPU has different max frequency with different CPU. Maybe this relates to the CPU or some other features? So when we compute the GFlops, we should consider the CPU part.
About question 2, the L1 and L2 cache are the sampler cache and is read only, I think this is different from the traditional L1 and L2 cache and I don't know how can use it properly in OpenCL programming. Do you have some advice?
I'm not sure about question 3 and 4, actually, I'm not sure if there is 4 L3 cache slides and each is 1.5 MB?
Thank you again, and happy new year！
Hello Merlion, I found the following information for you.
I'm still waiting for the information on questions 1 and 2.
For question 3 the information you gave us on your post is correct.
This is the best diagram of the processor that I found. At this moment, we have not released a detailed diagram for the L1/L2 cache architecture.
Thanks, Sylvia. Thank you for your help.
Merlion this is the information I received regarding question #4
There are good descriptions published when Haswell launched. Here is a good place to start: http://www.realworldtech.com/haswell-cpu/

Only the i7-49xx series Iris Pro Graphics 5200 skus have a max dynamic frequency of 1.3GHz. The i7-48xx and i7-47xx Iris Pro Graphics skus are 1.2GHz. Hope this is helpful
