how much would E5 have costed

so with mass market hardware, $200 approx gets you a card with 4tflops (4billion transistors), but thats 120watts .. not suitable for drones and so on

the 1024 core epiphany is at ~4billion transistors, that would also be 4tflops? (1024x2x2ghz perhaps) .. but I imagine consuming much less power for a problem that fits on chip

with sufficient volume, should it have been possible to get a 'parallela 2' into that sort of price range .. the ultimate device for drones etc

E5 is published to be 117 mm^2. Let's call that 9x13mm. If you use a wafer calculator to figure out many die candidates you can get per wafer, it's a little more than 500 on a 12" wafer. If the cost per wafer is $10,000, you end up with $20/E5. This is about the best case scenario and cannot go lower unless you run your own fab. It also doesn't count design, packaging, tapeout, masks, making a product, or profit. It's why it's often important to have a large market because those other costs can sometimes be large.

BTW, the 4 single precision TFLOPS number is based on 2 SP FMAs/clock at 1 GHz, not 2 GHz.

Do you happen to know anyone looking to make 100,000+ drones with 4 TFLOPS onboard?
