AMD Radeon R9 380X will be released on November 19th.
AMD Radeon R9 380X — 2048 Cores for 1440p gaming
The R9 380X features the same reference cooler as R9 380. However it is unlikely it will be offered with this design. Instead AMD add-in-board partners will offer customized models including:
- ASUS with STRIX R9 380X OC
- Gigabyte with R9 380X G1 GAMING
- HIS with R9 380X iceQX2
- PowerColor with PCS+ R9 380X Myst Edition
- VTX3D with R9 380X
- Sapphire with NITRO R9 380X
- XFX with R9 380X Double Dissipation
All these cards are shown in the slides.
AMD Radeon R9 380X has Tonga/Antigua XT processor with 32 Compute Units, 128 Texture Units and 32 ROPs. Each CU has 64 Stream Processors, so in total we have 2048 unified cores.
While Radeon R9 380 was offered in two versions: 2GB and 4GB, the R9 380X will only be sold with 4GB GDDR5 memory.
Surprisingly, R9 380X has the same TDP as R9 380 — 190W. However since TDP is not power consumption, we still can’t tell you how power efficient Antigua XT is. Hopefully that will be covered in detail by reviewers.
Radeon R9 380X supports all latest technologies from AMD. Tonga is on the same IP level as Fiji, so unlike Hawaii or Pitcairn-based cards, we get full support for VSR (including 4K VSR), DirectX12, Vulkan and Mantle.

AMD Radeon R9 380X performance
In official slides AMD took GeForce GTX 660 as a reference (don’t ask me why though). According to their internal benchmarks R9 380X is 2.25 times faster than GTX 660. In fact it’s even faster than overclocked GTX 960, however it will fail against GTX 970 or 780 Ti, but well these cards cost more for a reason.
NVIDIA has nothing really to compete directly against 380X, so I would be surprised if they were not planning 960 Ti very soon.
