gtx 1060 vs rx 480 hardware question!!

[Xanthosis]

why does 1060 has less spec than rx 480 ..i mean less teraflops ..but the performance are simillar ?? www.hwcompare.com/31137/geforce-gtx-1060-vs-radeon-rx-480/
so does the hardware matter for different arcitecture ???

Regarding Teraflops: one reason is because teraflop number in specifications for RX480 is for maximum boost clock, not for average operation. While for GTX1060 specs- teraflop number in specs is just some lower number, because it really runs at much higher average clocks than stated anywhere in specs.

Another reason: AMD has additional hardware- Asynchronous compute engines (ACE) in front of SPs (/Teraflops). This engine can help with computation by offloading some work from CPU to GPU, but it also acts a bit like a stop-light, making it harder to fully use teraflops unless programmed for it perfectly.

There are other differences: for example, nVidia has better color compression, and compressed data needs less bandwidth (so nVidia can use 192-bit bus, instead of 256-bit). Also nVidia has way higher pixel rate (can be useful for certain anti-aliasing) than AMD card- while AMD is tuned for doing anti-aliasing through SPs/teraflops.
