News AMD RX 460 and RX 470 announced

AMD have announced the RX 460 and RX 470 cards.

It looks like the 460 will be PCIE slot powered which should be great for SFF systems. Look forward to seeing the benchmarks.

The RX 470 is described as being a 1080p card, so perhaps similar performance to a 970?

the 470 being equal to a 970 seems a bit overly optimistic. I guess it will be more around the 960, although that's a bit interesting that it's "VR Ready" - could be they are doing some software improvements like what Nvidia has done on Pascal and removing the extra pixels from being rendered.

 

[K888D]

The 480 is said to be equal to the 980, so I don't think its that optimistic.

For example, the latest GTX 950 cards that are PCIe slot powered run at 75W on a 28nm process. So if AMDs RX 460 is 75W on a 14nm then it will likely be more powerful than a GTX 950 putting it more into the range of a GTX 960 (at a guess). So that leaves a gap between the 480 and 460 between a GTX 980 and GTX 960.

I'll give $50 to the site if the RX 480 can beat the GTX 980 in any AAA title.

In DirectX12?

 

[IntoxicatedPuma]

DX12 or 11.

Tomshardware have spotted that the RX 460 is a single slot card with quite a small heatsink, this would suggest that it probably runs well below the 75W power limit, uaully cards approaching 75W usually have dual slot coolers.

So you may be right @IntoxicatedPuma about where the 460 and 470 cards sit in performance levels, perhaps closer to the 950 and 960.

Single slot and low profile cards would be nice though.

A RX 470 single slot would be amazingly awesome, if it had performance close to a GTX 970, I would buy as many as I could. Even if it had performance slightly better than a GTX 960, I'd still buy as many as I could.

 

[K888D]

I think only the 460 will be single slot unfortunately, the 470 has a 6-Pin power supply so it will need a decent sized heatsink.

But the 470 PCB does look ITX sized, and the 460 is even smaller, barely longer than the actual PCIe slot.

Hopefully they will make some low profile versions, the low profile HTPC market is in need of something more powerful than the 750Ti along with all the other hardware updates such as H.265 decoding and HDMI 2.0.

Videocardz.com has released preliminary benchmarks for the RX 480 and RX 470

Low profile is definitely needed. The GTX 650 and 750 to had LP versions as did a 6850 (even if it was hard to find). We have hope yet!

The 460 seems to position itself to be somewhat more powerful than a GTX 950 (Nvidia also marketed that as a very MOBA-friendly card).

I'm more surprised (and ecstatic) that these cards will launch as soon as the end of June, alongside the RX 480.

MD confirmed the specifications of its Polaris10 "Ellesmere" and Polaris11 "Baffin" GPUs. The two chips will drive at least three desktop discrete SKUs between them, the Radeon RX 480, the RX 470, and the RX 460. Of these, the RX 480 and RX 470 appear to be based on the "Ellesmere" silicon. This chip features 2,304 stream processors spread across 36 compute units (CUs), and a 256-bit wide GDDR5 memory interface. The "Baffin" silicon, on the other hand, features 1,024 stream processors spread across 16 CUs, and a 128-bit GDDR5 memory interface

So RX 480 we know is 2304 stream processors, the RX 470 would likely be about 1280-1536 (just a guess) and the RX 460 will hopefully be a full 1024. So just guessing how they will match up performance wise:

RX 460 = R7 370 / R7 265
RX 470 = R9 380 / R9 285
RX 480 = R9 390

If the RX 460 can deliver GTX 750 ti performance at 30-40W, that's impressive. If the RX 470 is delivering GTX 960 (or even better) level performance at 70-80W, that's also really impressive. I guess the RX470 will be about on par with the GTX 960 OEM - the 192 bit 1280 core GPU?

 

[K888D]

I would expect the RX 460 to outperform the 750Ti.

According to the reviews of the GTX 1070 and 1080, when NVidia moved from 28nm (Maxwell) down to 16nm (Pascal) the performance per watt increased by around 1.6 times in real world testing.

AMD are moving down to 14nm so they should be able to (in theory) at least match NVidia on performance per watt.

The GTX 750Ti is a 28nm card with a TDP of 60W, this would translate into 37.5Watts using the scaling assumptions above (1.6x performance) if it moved down to 16nm.

If AMD can match NVidia's performance per watt, then a TDP of around 37W should outperform a GTX 750Ti and a TDP of around 47W should outperform a GTX 950, this of course is based on massive assumptions and very basic calculations on the limited data available!

Also using the above assumptions a TDP of 76W should outperform a GTX 960, and seeing as the RX 470 has a 6-Pin power connector then you would expect a TDP of at least 75W. If the RX 470 has a TDP of 90W then it should be comparable to a GTX 970.

 

[IntoxicatedPuma]

the RX 460 coming close to the GTX 950 sounds pretty reasonable I guess. I forget the 950 is now a 65W card and price is getting down well under $150. The RX 470 matching a GTX 970 still sounds kinda iffy to me. Even matching a GTX 960 OEM would be a huge coup for AMD at that price and TDP.

 

[K888D]

According to these benchmark results which Guru3D have worked out from AMD's presentation footnotes, the RX 470 will perform well above the GTX 960 and just under a GTX 970:

http://www.guru3d.com/news-story/radeon-rx-470-benchmarks.html

The slide in the Techpowerup article you linked above also states the RX 460 as having >2 TFLOPS performance, compared to the GTX 950 which has 1.57 TFLOPS and the GTX 960 has 2.30 TFLOPS. I know you cant directly compare TFLOPS for real world FPS performance, but its a good starting point.

If any manufacturers are listening - please release a low profile, slot powered RX 460. Thank you.

Slot power RX 460 is very probable, as that's the sample card that was show in the reveal. Also sometimes power ratings on paper are higher than their actual target limit.

I would expect the RX 460 to outperform the 750Ti.

According to the reviews of the GTX 1070 and 1080, when NVidia moved from 28nm (Maxwell) down to 16nm (Pascal) the performance per watt increased by around 1.6 times in real world testing.

AMD are moving down to 14nm so they should be able to (in theory) at least match NVidia on performance per watt.

The GTX 750Ti is a 28nm card with a TDP of 60W, this would translate into 37.5Watts using the scaling assumptions above (1.6x performance) if it moved down to 16nm.

Actually, the stock 750 Ti's already are capped to 38.5 W from the BIOS. The power target never get close to the 60 W spec when used in gaming, or even crypto mining, as miners have found out when using these cards. Power target limits are set to 38.5 W hard on 100% power.

There was actually more head room on these cards than most people realize. In theory, Polaris 11 could be even more efficient in actual performance.

The screenshot if from the stream here: https://www.twitch.tv/pcgamer/v/72241344 . The reveal starts at 39:19. I am really liking the look of these cards and would love to have a look at either the RX 470 or RX 480 when they're released.

GTX950 LP has been out for a few weeks. May not be that much better than 750Ti LP but at least those two checkboxes are ticked off.
