AMD GPU Rumors: Navi 12 ‘Radeon RX 5800 Series’ With 256-bit Bus & Navi 14 ‘Radeon RX 5600 Series’ With 128-bit Bus
There’s a whole bunch of new information for AMD’s upcoming Navi based Radeon RX series that would feature the Navi 12 and Navi 14 GPUs by 3Dcenter.
It looks like AMD would have a complete lineup versus the RTX SUPER series and the mainstream GTX cards with their own budget and high end options.
AMD Navi 12 & Navi 14 GPU Rumors – Navi 12 Built For High-End Radeon RX 5800 Series To Tackle RTX 2080, Navi 14 Based Radeon RX 5600 Goes Against Turing GTX Cards
So we know about the existence of both AMD Navi 12 and Navi 14 GPUs. They have appeared on GPU databases from time to time and we also got to see some specifications and performance of the mainstream Navi 14 based variants.
But we still don’t know how AMD is going to position these new GPUs and that is where 3DCenter’s forum member, Berniyh, comes in.
The user dug deep into the latest Linux driver for AMD’s graphics cards and found IDs for both, the Navi 14 & Navi 12 GPU.
619 case CHIP_ NAVI12 :
620 info-> num_sdp_interfaces = 16;
622 CHIP_ NAVI14 :
623 info-> num_sdp_interfaces = 8;
3984 if (AMDGPU_IS_ NAVI10 (pInfo-> FamilyID, pInfo-> eRevId))
3994 pInfo-> gfx9.numSdpInterfaces = 16;
via 3DCenter Forums
The two details mentioned in the listings are the pc_lines and num_sdp_interfaces. 3DCenter says that these two details would help distinguish which GPU is the high-end variant and which is AMD’s lower-end variant.
Just from the sdp_interface number, you can tell that Navi 12 is close to Navi 10 with 16 sdp_interfaces while Navi 14 has half the sdp_interfaces of both chips.
It is also stated that the SDP_interfaces number coincides with the memory bus and considering the Navi 10 GPUs have a 256-bit bus, so would the Navi 12 GPUs.
But Navi 14 would offer a smaller bus interface of 128-bit which seems in line with the more budget and entry-level design of this chip as we have seen so far.
AMD Navi 12 ‘Radeon RX 5800 Series’ GPU Specs
The AMD Navi 12 GPU is looking to be a much higher-end offering than the Radeon RX 5700 series. Hence we shall call it the Radeon RX 5800 series and as such, it is expected to compete against the NVIDIA GeForce RTX 2070 SUPER and the GeForce RTX 2080.
Based on the specifications posted by 3DCenter, the GPU could offer 30 to 50% more stream processors than Navi 10 which maxes out at 2560 SPs. If that ends up being the case then we can see a core count similar to the RX Vega 56.
Its also stated that the card would retain a 256-bit bus interface and would utilize GDDR6 memory but we can possibly see faster memory clocks resulting in higher bandwidth.
However, the source doesn’t rule out the possibility of getting HBM2 memory alongside Navi 12. It is also mentioned because having a 256-bit bus for a higher-end GPU might be slightly inadequate for the chip itself.
Although NVIDIA’s high-end GPUs like the RTX 2080 SUPER do feature a 256-bit bus and run great, the SUPER variant utilizes higher clocked GDDR6 dies (15.5 Gbps) compared to 14 Gbps of the normal variant.
Additionally, NVIDIA has multiple technologies that help bandwidth to be efficiently spread across the GPU. AMD could also use binned GDDR6 dies for the RX 5800 series or they can just go for HBM2 spread across a 2048-bit bus interface.
This would lead to a slight reduction in overall power consumption which could near the 300 Watt wall if GDDR6 is to be a preferred choice.
Based on the specifications, the performance uplift would be good enough to undercut the RTX 2080 SUPER considering the RX 5700 XT custom variants already come close to the GeForce RTX 2070 SUPER.
That along with a slightly lower price of around $550-$600 US would result in a great product for high-end users.
THX to WCCFtech
I don't see AMD putting HBM2 on a higher-end variant of Navi10 so probably GDDR6 though at 256-bit or rather SDP Interfaces at 16 then if it's 256-bit that might hamper bandwidth and overall GPU performance but from what I am reading Vega also had 16 specified though using HBM and depending on type of HBM including the newer variants it might be possible to manage costs a bit though re-engineering the GPU to do HBM fits more with Navi20 than a higher-end variant of Navi10 plus the naming scheme could end up being a 5600 and 5500 instead of 5800 and 5600 but we'll see shortly I suppose.
To clear out Polaris stock and make room for replacements for the 500 series at 5500 and 5600 or to aim for high end with a 5800 and compete against the 2070 or 2080 (Might be a bit optimistic?) well either one could work and Polaris retaining a lower cost but still well performing GPU choice with Navi then taking over Vega and moving to compete with NVIDIA although that's also something I see happening more with the Navi20 but then NVIDIA might be closer to revealing their own work on what they have for 2020 and could also cut pricing of the 2000 series or certain GPU models to clear out existing stock while also interfering with the whole price/performance ratio of AMD's GPU's compared to NVIDIA's closest priced alternative.
Going to be interesting to see how it turns out.
(Personally I am expecting higher-end to be for next year and AMD populating mid range with these two leaving Navi10 at the high-end segment but I could be wrong.)
EDIT: But a 5800 for early next year and the 6000 series (Or whatever it will be named.) for near the end of 2020 and Navi20 could also be a possibility, guessing AMD has a roadmap but for now just waiting and seeing what gets unveiled or occasionally also leaked or revealed via the Linux drivers and other sources.
Yeah forget there are several versions of GDD6 and the most expensive but still cheaper then HBM.
Samsung’s GDDR6 delivers maximum bandwidth and blazing-fast speed of up to 768GB/s. The 5700 XT only came with about 448 GB/s at stock.
That's BS from wccftech . 5700xt is already in par with 2070 super. 5800 should be against 2080 and 5800 xt against 2080 super.
Or better performance. Why base a card release against something that is already out, and doesn't hit the mark? By mark, I mean 4K@60 Ultra.
The 350-400 mm² "Navi 12" is a whole different beast, with an estimated 64 compute units (4,096 stream processors).
The big news in the 3DCenter.org report concerns its memory interface. AMD will stick to 256-bit GDDR6 memory with the "Navi 12," and probably dial up memory clocks compared to the 14 Gbps speed the "Navi 10" uses.
This design choice is influenced by NVIDIA's decision to stick to 256-bit bus width with its "TU104" silicon.
As always, if i like it (and it fits our Thread) i will post it.
Just Copy/Paste as always, im not making any $ on this.
Is just for Us to have it in one place in order, don't be.... mad about it.
Link TPU if you are going to nick their stuff, again.
Also, DO NOT LINK TO THEIR IMAGES ON THEIR SERVERS (aka cross-site linking) !!!
If you nick the image, re-host it somewhere like IMGUR or something, and link back to the original page for source.
They don't pay for their servers bandwidth, to provide images for other sites.
This is like THE big NO-NO for posting.
Sorry for being a bitch about it, but its just not right.
There should be links for all content posted to get a complete view of what is being said.
You can't compare by performance at X,Y,Z settings/resolution. Nvidia always has and had larger dedicated GPU market-share than AMD. It is only logical. And, 4K@60 Ultra/Ultimate is for 2080ti overclocked. Even stock cannot reach it. So we are talking about 4K@High/V.High settings.
1) Larger market share on PC. This is shrinking. AMD already owns consoles.
2) Having to OC a card to hit 4K@60 Ultra isn't hitting the mark. Even 4K@High is spotty on 2080Ti, so no I consider the 4K@60 mark hasn't been reached yet for AAA titles. (Looks at UE4 engine for prime example)
3) Going forward, I will never ever own a NVIDIA solution again. Panel whitelisting to enable GSync on laptop screens still is an issue, despite NV stating this behavior was changed in their drivers, making panel upgrades a PITA needlessly. Tired of NV holding VRR hostage for license fees. Looking forward to see what Navi/Arcturus brings to the laptop side.
Any credible rumors on a release date for Navi 12? I really want a little more horsepower than the 5700 XT, and I can afford to wait a few months. If it's going to be Q2, I think I would go with a current card and trade up in a year or so.
EIZO Introduces Limited Edition Foris Nova Dsplay: 21" 4K OLED, HDR, and 60Hz
EIZO today announced a limited edition monitor that's sure to attract attention: likely positive due to its feature-set, likely negative due to its small diagonal. The Foris Nova is built fully in aluminium and packs an impressive amount of features for the admittedly small diagonal: the 21" display is a 4K OLED one with a 1,000,000:1 contrast ratio, 330 nits maximum brightness and 1.07 billion colors. That small diagonal does have its benefits though: the pixel density is a very impressive (for desktop monitors) 204 pixels per inch. The 60 Hz refresh rate is nothing to glow at, but the 0.4 ms response time surely point to an amazing 60 Hz gaming experience.
There is HDR certification in the form of HDR10 and the royalty-free Hybrid Log-Gamma (HLG), and connectivity is taken care of by 2x HDMI ports that support Deep Color and the HDCP 2.2 and 1.4 copy protection protocols. There are two 1 W speakers, VESA support,1x headphone jack and 1x line-out mini jack. The production is limited to only 500 units, and the Foris Nova will be available from November 1st in the U.S., Europe, China and Japan.
No word on pricing yet.
I'd say at the very least March, for CES ?
Samsung reveals 12-layer 3D-TSV chip breakthrough - Huge implications for HBM memory
Samsung Electronics has announced that they have successfully developed the industry's first 12-layer 3D-TSV (Through Silicon Via) technology, creating packages that are the same thickness as today's 8-layer HBM2 (High Bandwidth Memory-2) chips.
Using 60,000 TSV holes, Samsung can vertically stack 12 DRAM chips to create a three-dimensional structure, allowing the company to develop HBM memory chips that are up to 24GB in capacity.
Also, by increasing the number of stacked layers from eight to 12, Samsung will soon be able to mass produce 24GB High Bandwidth Memory, which provides three times the capacity of 8GB high bandwidth memory on the market today.
This feat is accomplished by stacking 12 16Gb chips. Amazingly, Samsung has been able to achieve this without any increase in size over today's 8GB HBM2 memory packages.
Thanks to the shorter data transmission time between chips, Samsung's 12-layer 3D-TSV technology can also enable faster memory speeds and lower levels of power consumption than existing wire bonding technologies.
With this new technology, Samsung's HBM2 memory could be used to create a Radeon VII-style graphics card with up to 96GB of HBM2 memory.
Today, HBM2 memory is popular in a variety of use cases that extend from graphics cards to FPGAs and AI accelerators.
Offering high capacity HBM memory modules will enable these products to work with larger data sets, which will in-turn help to push these technologies forward.
At this time, Samsung has not revealed a release timeframe for its 12-layer HBM products, though we expect to hear more in the coming quarters.
THX to OC3D
There are now three THICC II models: THICC II (57XT8DFD6), THICC II Ultra (57XT828D6) and another THICC II Ultra with a different product code (57XT8DBD6).
There is also an RX 5700 version called Double Dissipation (57XL8LBD6).
The THICC III Ultra (57XT828D6) is one of the fastest RX 5700 XT on the market. Based on our research it is only slower than ASUS ROG STRIX OC (with a peak clock at 2035 MHz).
The THICC III Ultra has a peak clock of 2025 MHz (please note that in our database the Navi boost clock is AMD’s game clock – as it should be).
Sony announces PS5 name & release date:
Up to this point, Sony hasn’t officially confirmed the name or when to expect the release of its next-generation game console.
That changed today, however, with confirmation that its next-generation console will indeed be called the PlayStation 5 and it’s scheduled to release in the Holiday season of 2020. While we won’t get our hands on it for about a year, it’s packing some very interesting technology under the hood.
In a story by Wired, Sony Interactive Entertainment CEO Jim Ryan said that the console will stick to the simple naming conventions of past consoles, and it will release in the holiday season of next year.
Ryan was joined for the interview by system architect and Knack mastermind Mark Cerny, who clarified that ray tracing will be possible on the system through GPU acceleration.
The PS5 will come with a 4K Blu-ray player and discs will be 100GB in size. This should eliminate most needs for more than one disc on retail releases, though certain titles could cross that threshold — this generation’s Red Dead Redemption 2 narrowly missed being that large at launch last year. You’ll be able to choose what you install from a game, however, meaning if you are only interested in the campaign, you won’t have to waste time with the rest of the game and have it take up space.
The PlayStation controller will be getting something of an overhaul for the PS5, as well. It will feature “adaptive triggers” with resistance based on your activities as well as haptic feedback that is more lifelike than the rumble found on most controllers today.
This can even affect the analog sticks, and the larger battery being installed in each controller should help with the poor battery life that has plagued the DualShock 4 this generation.
The PlayStation 5 is shaping up to be a powerhouse that can go toe-to-toe with Xbox Scarlett, and development kits are in the hands of developers right now.
Among them is longtime Sony partner Bluepoint Games, which said it is working on a “big one,” but did not clarify what that meant.
Past projects have included remastered and remade versions of games like Uncharted: Drake’s Fortune and Shadow of the Colossus.
Some have speculated its next project could be a new version of Demon’s Souls, which is celebrating its 10th anniversary this year.
That right there along with full backwards compatibility will get a buy from me!
One last run of RX580 to see how the Polaris come a long way before its replaced with RX5500 in next few days.
Take a look at this :
