Conclusion

This is a GPU most comfortable at 1080p with medium/high-quality settings.

The AMD Radeon RX 460 GPU is a not-quite-full implementation of the Polaris 11 GPU. This 896-core part is designed to meet the needs of the would-be gamer taking their first steps into proper graphics.

Pressed by a need to produce a small, energy efficient GPU, RX 460's benchmark performance is akin to a readily available GTX 950 and substantially lower than an RX 470 based on the fuller Polaris 10 die.

This is a GPU most comfortable at 1080p with medium/high-quality settings. As such, it needs to be priced this way, so the £130 asking fee for 4GB-equipped models is too steep when all else is taken into account. It makes most sense outfitted with 2GB of memory and costing no more than £100, and we encourage manufacturers to target this space aggressively.

Sapphire understandably needs to build cards with various frame buffers and features. The RX 460 Nitro is a very solid card that envelopes a GPU whose price-to-performance ratio isn't the best.

Faster than I expected - shame it is isn't the full Polaris 11 GPU with 14% more shaders. I agree it needs to be cheaper too.
Yeah, seems to perform well. I spottted some leaked numbers a couple of days ago that put it some way behind a GTX 950, but obviously not.

Ebuyer seems to have the best supply of cards, including a powercolor in stock at £99: http://www.ebuyer.com/754200-powercolor-red-dragon-rx-460-2gb-gddr5-dual-link-dvi-d-hdmi-displayport-pci-e-axrx-460-2gbd5-dh-oc

EDIT: also, was worried that Sapphire saw fit to give it a power connector, but it looks like that's mostly for overclocking performance given the power draw figures…?
So a different conclusion is that the 2GB £100 version should generally beat the GTX 950 OC for £30 less?
Do we suspect AMD is keeping the full-die 1024 shader chip for the launch of its mobile-gpu products?

Additionally, presuming we do eventually get a a desktop sku with 1024 shaders, might we hope it will come with 4GB and (some models at least) a 75W TDP?

Depends on implementation, and whether a 2GB frame-buffer would hold it back in any games. So far there doesn't seem to a be a 2GB card reviewed anywhere (nor one without a 6pin power connector), so it' shard to be sure…

Certainly possible - they don't need to restrict power usage so much on the desktop and I suspect they can qualify more dies at 1200MHz if they disable a couple of shader blocks. I suspect the mobile parts will run a fair bit slower on GPU clock and pull a fair bit less power, but perform similarly due to the higher number of enabled shaders (think of the comparison between a Fury and a Nano, for instance).

With 4GB, almost definitely. With a 75W TDP, I'm doubtful - Tom's Strix 460 pulled 90W during gaming with a 1256MHz core, which isn't a huge overclock (< 5%), and power draw usually scales linearly with clock speed. I suspect that a reference RX 460 @ 1200MHz can pull over 80W, and is likely to hit its power limit fairly hard, scaling clocks back 10% or more…
