or if you're actually serious, why not compare the actual arrangement of those components?
Lol, obviously they're different. I dont think he was trying they're exactly the same thing, but to say that tonga brought no real benefit over tahiti to consumers.

For all intents and purposes when referring to performance and bemchmarks, tonga = tahiti. It replaced tahiti at the same price, and offered the same performance. How they achieved the same performance at the same price is arguably irrelevant.

i'm not sure if you're joking or not.

first off, TahitiXT rebrand 280X was priced $299 on launch, where as TongaXT 380X was priced $229 on launch, they're by no means "at the same price".
second, 3rd Gen GCN introduced not just a few new features, but also extended the instruction set support, it supports OpenCL 2.0 instead of OpenCL 1.2.


the improvements on Tonga isn't targeted for raw performance, but for feature compatibility, Tonga simply supports more things that Tahiti doesn't.

380X is not HD 7970/280X rebrand.

I didn't say launch msrp vs launch msrp. The 285 launched at the same price 280/280x was AT THE TIME. Which only made sense since it offered practically identical performance to the 280. The 380x launched what, a year later? Or, 2 years after the 280x, 3 1/2 years after the 7970 ghz. Offering practically identical performance. Is it a bargain because it didn't launch at $499?

My whole point was that features that don't improve performance are useless when using the card as a reference for peformance. On benchmarks they are the same in all but name.

because thats a flawed comparison, you aren't comparing it apples-to-apples but apples-to-oranges.
its very obvious that they'd drop the price of old gen hardware just to get it off the retailer's shelves, otherwise old gen hardwares will just rot there unsold.
or to put it in an even more blunt way, they're trying to get rid of old gen hardware even if its priced at a loss, it is worth it for them rather than getting nothing at all.

thats an even more flawed comparison, and a silly one at that, by your logic 380X wouldn't even be any better than 280X.
e.g. if you had to choose between 280X and 380X which would you choose?

The 380x is actually Tonga XT, a full 285/380 which was Tonga Pro. The 280x is re-branded 7970 which is Tahiti. Tonga has delta color compression and other minor tweaks.
"minor tweaks" indeed; same ish different year; TFLOPS don't matter with AMDs trashy drivers
AMD has been trying to improve them in the past year which is nice, but Nvidia still beats them badly in the software department.

I think Nvidia has always relied/focused more on software, while AMD relies on hardware.

AMD drivers are pretty good these days, and actually, it's the other way around. Nvidia brute forces their way through with hardware (see Pascal just a higher clocked Maxwell), while AMD cards get better performance as time goes on with drivers.

pretty hard to complain about Pascal hardware though when they can have a 314mm2 die beat the 980 by ~65% redface.gif

28 vs 16nm. redface.gif

it should have been 100% if they put some effort on increasing ipc.

now you're just asking the impossible redface.gif 16nm or not, its just 314 mm2 .. if 1080 had 398 mm2, we'd be close to 100% thumb.gif

Got up two hours earlier to see if I could snag a RX 480 in Canada this morning... nope.
