right now P10 (232 mm2) loses to Pascal (314 mm2) in raw perf / mm2, we'll see if something changes with a hypothetical 480X or Vega
At this point it's pretty much confirmed 480x doesn't exist.

I'm an sorry, but this statement is incorrect. I am not going to argue with you about it.

performance is a measure of voltage in pc's, at the expense of power consumption. This is why the TSMC apple chips were more power efficient than their Samsung parts. Tsmc chips operated at a slightly lower base voltage, compared to the samsung/glofo node.

it's not a low power node, they call it a low power node, because it's more efficient than previous planar soi designs.

Can someone explain to me why perf/mm2 really matters for these cards? Imo only perf/watt and perf/$ matter here.

Ppl said the same with full Tonga. It will eventually come out when the node is mature

its up to you to decide if thats sufficient or not

I currently use a MSI gaming 290x at a mild OC at 1440p 70hz and I don't play a hugely wide variety of games but I can usually have settings to high-ultra with low to medium AA. With the RX480 projecting to perform slightly better than that 290x I think it will be great for 1440p high-max settings. If your monitor is not gigantic it is hard to tell between 4x and 8x AA anyway.

It's irrelevant when you compare the volts between 2 different nodes. It's like comparing the volts of a SOI node to finfet.

There isn't any argument here. Doesnt change the fact that gpus are high performance parts and amd is using a mobile soc low power node.

I will correct you one last time.

It's not a low power node. AMD is releasing Zen on this node, a high performance cpu, they are releasing high performance gpus on this node. Why would they gimp themselves? it makes absolutely zero sense, much like your statements.

Performance is a measure of voltage. I will repeat that statement. TSMC 16nm- base voltage 0.70 volts, Samsung 14nm- base voltage 0.800 volts, Intel 14nm- base voltage 0.75 volts. The reason they call it "low power plus" or a low power node is because of Finfet. With finfet designs you don't need as much voltage to get high performance. This allows you to reduce the total voltage, improving efficiency and keeping high clocks.

Base voltage of the 28nm node is between 0.6 and 1.1 volts, 0.6 is the ultra low power stuff, and 1.1 is the super high performance stuff.

ok so if 28nm high performance took 1.1 volts, and the finfet 14nm takes 0.800 volts you can clearly see why they call it a low power node. Again it doesn't mean they cannot reach high clocks because finfets don't need no where near as much voltage to achieve higher clocks.

Oh if only @The Stilt was here... And do you expect zen to match the clocks of intel ?

I will stop it here because you have zero idea about nodes thumb.gif

It's not important for us, but it is important to AMD.
The smaller the chip is, the cheaper it is to produce, and the faster you can produce large volumes.

lol rolleyes.gif

you're a waste of time to try and educate. I didn't say AMD will match the clocks of intel, there are other factors other than voltage.
