Sapphire Readies Third Variant of Radeon RX 6750 XT GPU
AMD's RDNA3 Navi 32 GPU is reportedly in the works, but PC hardware enthusiasts are getting frustrated with the lack of announcements in regards to Team Red's supposed mid-to-high level "Radeon RX 7700 & 7800 series" card offerings. Current generation options are only available in the form of pricey flagship models - RX 7900 XT and XTX, as well as the recently released lower end RX 7600, with nothing classed as brand new appearing in the middle ground. Notable AMD board partner Sapphire Technology is also getting impatient with this situation and has decided to dip back into RDNA2—technology news site ITHome has discovered that the company is releasing another Radeon RX 6750 XT 12 GB GDDR6 card. This third variant follows previously issued NITRO+ and Pulse models.
Sources have indicated that this new model is called the "Overseas Edition," so it is possible that it will be getting international distribution. Sapphire's custom card has not hit the South East Asia market yet, and the company has not created (at the time of writing) an entry for it on their website or product catalog. ITHome reckons that the Radeon RX 6750 XT Overseas Edition will likely get a retail release to coincide with this week's 618 shopping festival. The card seems to offer a marginal performance advantage (0.9% factory set overclock) over AMD's reference specs—with a 2623 MHz boost clock. It shares the same features as its NITRO+ sibling—namely a Dual BIOS switch and two power connectors.

It's an odd suggestion and it doesn't even make sense as presented, and that should have been obvious to anyone writing for this site.
TL;DR:
Navi31 works, but not as well as AMD wanted it to. Navi32 will be AMD's revised, second attempt at the MCP memory chiplet design, but the revision likely adds at least 6 months to the schedule and Navi32 was always going to be a 2H23 product even before news of this revision.
There's no concern over the latency of the L3 cache on Navi 31. It is well established that larger caches are slower. This is the entire reason for cache hierarchies in the first place. Conventionally, cache L0 is the smallest and fastest and cache L3 is the largest and the slowest. Let's look at the L3 cache sizes of Navi 31 and Navi 33:
Navi 31 - 96MB of L3
Navi 33 - 32MB of L3
We can see that Navi 31 has THREE-HUNDRED PERCENT MORE L3 cache. We know that Navi 31 L3 cache access is 58% slower, giving us a nominal L3 access time of 1.58 per trip compared to Navi 33's 1.00 per trip. However, Navi 33 needs to make THREE trips to access 96MB worth of L3, so it would have an access time of 3.00. And this is only talking about the cache.
VRAM on Navi 31 has over 330% more throughput than Navi 33.
This was covered (by me) on TPU last week, based on very impressive and thorough tests conducted by Chips and Cheese.
Why all the fuss in here? The card is still performing as intended. It's sold off to cover a certain price performance.
I know what I am saying, cause I am on the internet.
