AMD Radeon RX 5600 XT Features 2,304 Stream Processors
AMD's upcoming Radeon RX 5600 XT graphics card features the same exact stream processor count as the $350 RX 5700, according to a leaked specs sheet of a an AIB partner's custom-design graphics card. With a stream processor count of 2,304, it's safe to assume that the RX 5600 XT is based on the same 7 nm "Navi 10" silicon as the RX 5700 series. What set the RX 5600 XT apart from the RX 5700, besides lower clock-speeds, is the memory subsystem, which is severely stripped down. The Radeon RX 5600 XT will be equipped with 6 GB of GDDR6 memory across a 192-bit wide memory interface. What's more, the memory ticks at 12 Gbps, compared to 14 Gbps on the RX 5700 series.
With these specs, the RX 5600 XT has 288 GB/s of memory bandwidth at its disposal, same as NVIDIA's GeForce GTX 1660 Ti. In contrast, with 8 GB of 256-bit GDDR6 running at 14 Gbps, the RX 5700 enjoys 448 GB/s. The specs sheet suggests that AMD has also dialed down the engine clock-speeds (GPU clocks) a bit, with up to 1620 MHz boost, up to 1460 MHz gaming, and 1235 MHz base. With these specs, it's highly likely that the RX 5600 XT outperforms the GTX 1660 Ti and gets close to the RTX 2060. It all boils down to pricing. The RX 5500 XT is a decent GTX 1650-series alternative with a lukewarm price thanks to NVIDIA's aggressive product-stack management by getting its partners to lower prices of the GTX 1660 and GTX 1660 Super. It would be interesting to see if AMD can outfox NVIDIA in the sub-$300 market.

If they can avoid the 5500XT pricing blunder, and put it at around 250-260 USD mark would be great. That would make the 1660super and 1660Ti a tough buy.
AMD is using up those thousands of Navi 10 dies that didn’t meet the requirements to qualify for the 5700 SKU basically.
Smart Move,
But I agree AMD needs to rethink its overall GPU pricing.
Promising card indeed.
There is massive gap in both performance and price in the amd product stack, bud. Makes complete sense.
rdna2 and ampere are coming.smart move,lol,this is the same chip with less vram
it makes absolutely no sense for amd to sell a sweetspot 1440p card like 5700 with 6gb vram and a heavily gimped bandwidth,they should sell them as 5700s
the only thing they save here is 2gb vram,if this ends up too close to 5700 price wise nobody's gonna buy it.right,but to sacrifice a better die to gimp the memory and sell it cheaper,man,that's not a good approach.
a smaller die with 8 gigs and better bandwidth would be a lot better
I don't think RGT/AMD would sacrifice the memory Bus to save on only the cost of 2Gb of memory, there's probably a reason in quickly fusing off one complete shader engine, and then only needing to surgically cut a few stream processors in the remaining 3 engines. Given their New Compute Unit Design the time/effort to sit there and effectively gimp almost completely the shader engine, which probably leaves less of the use of that segments memory controller is easier. It's faster and lowers the chance in destroying the whole chip, just to fuse-off a complete shader engine.
Now sure the lack of 2Gb of "top-shelf" 14Gpbs "expensive" memory (and some are predicting GDDR6 prices to rise) but what if it aids in warding off supply issues, from perhaps price-hikes, while still deliver perf/price other cards won't if GDDR6 issues arise. I think AMD/RGT is making the most of their cramped TSCM production and this will provide a viable competitor and a $250 price point, until all the CPU/GPU 7nm production they have levels out. From Consoles, to Apple parts... to Ryzen 3 AMD/RGT have to juggle what wafer starts go where.
Against Nvidia to be perhaps 30% better than working off older 12nm process TU116; there's the GTX 1660 with 6Gb of GDDR5 from the same 192-Bit. Effectively very much the same vain as what AMD/RGT is doing now, but giving it 12Gpbs GDDR6 effectively doubles the bandwidth. If able to hold a $250 MSRP AMD/RGT verses that TU116 original MSRP it will be just 10% more in price that's a great value. From that understanding... those who paid-up for a GTX 1660 last April got swindled, paying "Top Self" price for process/technologies that were vintage, though computer part aren't like fine wine. Then vying the GTX 1660 Super or TI using GDDR6 (and same 12nm TU116) if the RX 5600 XT is 10-15% faster then it aligns perfectly with those. Then "Top" GTX TU116 parts are more often priced higher than the Super's $230 MSRP, while GTX 1660 Ti price at $270 and up here in the US today. AMD/RGT is in a good spot...
That being said this card makes sense. The entry cards get a stronger core than they would of otherwise and amd off loads chips that otherwise would of been waste.
Price: performance....time will tell how that stacks up I guess.
Who knows, maybe if these outsell expectations we will be flashing them with mod'd BIOS for full power limits?
In either case, wide and slow means that the efficiency should be good. And if they are doing this to reuse some failed 5700s rather than just cutting a good chip for market segmentation, then it is a good way to recoup the 7nm fab costs.
