Hi David,

Did my previous reply have answered your questions?

Or you still got questions regarding that?

Hi David,

For the die area, I think you can refer to FPGA package. For example:

• https://www.intel.com/content/www/us/en/docs/programmable/683458/current/fpgas-and-socs-f-series.html

Your calculation on DDR4 bandwidth should be okay.

For the embedded memory, you may refer to the link below:

• https://www.intel.com/content/www/us/en/docs/programmable/683241/25-1/embedded-memory-features.html
• https://www.intel.com/content/www/us/en/docs/programmable/683458/current/key-features-and-innovations-in-fpgas.html

For DDR4 memory, i have this equation:

DDR4 Memory Bandwidth = (Data Rate (MT/s) * Bus Width (bits) * #channels ) /8

Based on the F-Series product table I calculated the DDR4 memory bandwidth as follows:

DDR4 Memory Bandwidth = (3.2) * 64 * 4) / 8 = 102.4 GB/s

Does this make sense?

For the M20K and MLAB, I don't know what formula would be use to calculate bandwidth.

Hi David,

For your question about local memory bandwidth, memory bandwidth and die area of the part, are you looking for M20K, MLAB or EMIF? Or another memory?

Hi,

Please ignore previous post.

Peak FP32/FP16 FMA TFlops:

Peak FMA TFlops = (Number of FP Units × Clock Frequency in GHz × 2)GFlops / 10^12

Peak FP32/FP16 TFlops:

Peak TFlops = (Number of FP Units × Clock Frequency in GHz)GFlops / 10^12

Peak FP32/FP16 TFlops / mm^2 of fabric:

TFlops/mm² = Peak TFlops / Die Area in mm²

Shows example for AGF027:

From here, https://www.intel.com/content/www/us/en/content-details/690880/agilex-7-fpgas-and-socs-f-series-product-table.html

can get total DSP is 8528, FP32/FP16 fmax is 750mhz/0.75ghz (refer here https://www.intel.com/content/www/us/en/docs/programmable/683301/current/dsp-block-specifications.html )

FP32 Peak FMA TFlops = (8528*0.75Ghz*2)GFlops/10^12 = 12.8TFlops

FP16 Peak FMA TFlops = 12.8*2 = 25.6TFlops

I'll research and post later the rest formula.

Thanks,

Hi,

Seem like a gpu problem. Could you post here https://community.intel.com/t5/Graphics/bd-p/graphics to get help?

Thanks,
