AMD Readies Radeon R9 380X, XFX Ready with Card

AMD is readying a new SKU to take advantage of the vast pricing gap between the GeForce GTX 960 and GTX 970, and to bolster its sub-$300 lineup, with the Radeon R9 380X. This SKU will be based on the 28 nm "Tonga" silicon, which implements the latest Graphics CoreNext 1.2 architecture. The R9 380X could max out the specifications of the "Tonga" silicon, offering 2,048 stream processors spread across 32 compute units, 128 TMUs, 32 ROPs, and a 384-bit wide GDDR5 memory interface, holding either 3 GB or 6 GB of memory.

Another equally plausible theory pins the R9 380X as a chip with 2,048 stream processors, but the same 256-bit GDDR5 memory interface of the R9 380, with 4 GB of memory, letting AMD keep the costs low. XFX appears to be ready with a "Double Dissipation" card based on the R9 380X. The card's new-generation Double Dissipation cooler features an aluminium fin-stack heatsink with four 8 mm thick nickel-plated copper heat pipes, and a pair of 100 mm spinners, which are easily detachable, letting you clean the heatsink underneath. Mass-production of the R9 380X is reportedly underway, so a launch is to be expected rather soon.

No they are already bought. We just try to hide it from you.

Ferrum Mastermain question... how well it clocks... the clock decides the fate of this card... if it is past 1200MHz, it will be a stellar thing for the price.

And yeah... 6GB is useless... 4GB is okay for everything now, especially in the middle tier.
But it's welcome if the 6GB is 384bit memory instead of 4GB of 256bit memory. I'll take the wider bus and larger capacity, thank you.

The thing with XT AMD chips is that they're often overpriced for the performance increase they offer. The 390X is 10% faster than 390, but almost 25% more expensive. The 380X will be likely 15% faster than 380, but you'll surely have to pay at least 50 euro premium for that, which is again over 20% of the 380's current price. In the end instead of waiting for the Tonga I actually went with the 390, cause it's more fairly priced compared to the 380 - 50% more cash for a 50% performance increase. Yeah no GCN 1.2 compression, but with 512bit/8GB VRAM setup who needs it ^^

Thats the case ALWAYS and for every company when you have two products. The one performing faster will always cost more than what it offers. If it doesn't the cheaper model will not make sense and will not sell. For example 970 compared to 980, and before you tell me about the 390 example compared to 380, the same is true with 980Ti compared to 980.

Ferrum MasterTonga has IPC boost...

If we peek up at the Hilberts chart for the useless R9 380. OC at 1.1GHZ. And stock 990MHz. Additional shader cluster and more speed... it demolishes the old grandpa 280X. And how well additional 100MHz gained boost.
May I ask what makes R9 380 "useless"?

Existence of 7970.

Well, technically the R9 380 = the r9 285, the Tonga chipset, not the Tahiti. biggest difference is the newer GPU Architecture which supports Freesync, Dx12, and 3 monitor support without the need of a displayport or DP adapter. The 380 4GB is the upgraded version of the older 285 2GB.

The 380 4GB is my personal favorite from this lineup, its a beast at the price point and feature wise, i find it far more relevant that the 280 series launch in 2013.

Well Tonga really sucked at OC. And overclocked Tahiti mops the floor with it... I owned a 7970 and know it well. It was a stellar card btw. Tonga was a misunderstanding really. I had to clock high just under Hawaii pro performance, but it didn't... it was worse than the previous gen. Even with 7950 breathing in the neck.

The DP are kind of out of place for a mid range buyer really... 3 monitors on a Tonga? Really? Especially then the 2GB one. For what? 60FPS? Flight simulator won't run? Dirt won't run... What else? Some old exotics? Wow? It will stutter sub 60FPS on triple 1080p setup. And I don't really see any worthy LCD without display ports really... Zero problems there.

The idea is... you still can pickup a R9 280X and it will perform better... they cost the same... and that's a bit bonkers rendering this card useless.

See the OC charts from Hilbert. Well 10FPS more is 10FPS more... ain't it... ?

I had a 7970 Ghz ed it did not have better core clock than the average Tonga. Also it pulled more power.

Average Tonga is under 1Ghz and your 7970Ghz on stock is over that already...

Average Tonga with 1792 SPs clocked at 950mhz is equal to a 1050mhz 2048 SP Tahiti. A 2048 SP Tonga at 1Ghz will significantly beat the 2048 SP Tahiti while pulling less power and supporting all the new features that GCN 1.0 doesn't like Fsync.

The 380X makes sense.

How does it not? It's replacing the 280 not the 280X.
