AMD Execution Thread [2023]

Not useless for joystick users or consoles though

Fast mouse movement equal fast joystick movements as well. The idea is any scene with busy movement or graphics. As It will rely on Radeon Boost to function (which is part of the Hyper-RX tech), Radeon Boost drastically reduces the resolution of the game during motion and heavy scenes, and restores it during static scenes, so this makes frame generation practically useless and artifact ridden. Especially as it loses access to important game data.

Joysticks and mice are leagues apart. When they say fast mouse movement they are likely referring to competitive fps snap mouse speeds. Most console games don’t perform like that.

No, they refer to fast scene changes, irrespective of mouse or joystick. It's how Radeon Boost operates.

While a valid point you're looking at a new product with all the ads and marketing now while the 6800XT being available (in some places, not everywhere) at $500 was very much a retail only thing which most people probably didn't even realize.

I don't think the marketing will be very relevant given AMD's brand power TBH.

Wait until you see things in action first. If it’s that unstable they won’t bother with it

When are the Zen 5 processors supposed to come out?

They already bothered multiple times before: Radeon Chill, Radeon Boost, and Radeon Super Resolution (driver side FSR1). None of them is stable or delivers quality output, or super useful.

This driver side frame generation will rely on FSR1 (which already looks bad enough) and Radeon Boost (which dynamically reduces resolution in busy scenes), on top of that, It already lacks motion vectors for FSR2 (lacks FSR2 entirely), and lacks important information for FSR3 (sudden scene changes, UI elements, camera movement, depth information, etc), and on top of that, it stops working with fast camera movements/scene changes. You can't bake a good cake out of that recipe. The limitations are clear.

I would say the bigger argument is: It's likely meant for older games? And for older games you'll rarely have a desire for frame generation?
It also lacks support for Vulkan and OpenGL it seems? Surely no killer feature, but maybe still nice to have in some rare cases.

BTW, personally i've never tried any of such driver side features (Chill, Boost, etc.) at all. Neither demand nor interest.
The only killer feature AMD has added to the driver is disabling all hot keys with one click. Now i can use Photoshop again without getting mad each time when using a kb shortcut. Thanks for that - it really was needed.

This is the anti lag thing @DavidGraham is talking about, if this is used with frame gen in the global toggle the image quality while panning/turning could be pretty bad. Guess we just have to wait and see how it all turns out.

AMD rep says RDNA3 lineup is now complete, they won't release any more SKUs.

Scott: Well, the RDNA3 portfolio is now complete. Of all products that we have planned to launch, that is, this is the last few products that we will launch. We may have some different versions, but they are not a new ASIC/SKU. […] It’s been a journey, it’s been about a year since we launched the very first RDNA3 and now we are a year later finishing up the series. We should be done, we are done and we are excited. And now I think we have a broad spectrum covered for people who want RDNA3 up and down the price tag.

Mobile SKUs appear to be confined to N33, with no higher SKUs planned.

There's no word on the mobility side either which means that Navi 33 is the best that AMD has to offer to gamers with reports of a possible Navi 32 variation coming to mobile a distant dream now

AMD Has Completed Its Radeon RX 7000 "RDNA 3" GPU Family But Hints At Refresh

AMD has confirmed that the Radeon RX 7000 "RDNA 3" GPU family is now complete & no additional SKUs are planned though we might see a refresh.

Compared to RDNA2 lineup, which had 9 desktop SKUs + 3 refreshes, the RDNA3 lineup only has 5 desktop SKUs. So AMD appears to be scaling back their operation, which could lend credence to the rumors of RDNA4 skipping high end.

Seems like the normal corporate speak, especially after a long delayed launch.

They obviously have a huge gap in the $300-$400 market and a cutdown N32 at $350-$380 would fill it nicely.
Also, really strange that there wouldn't be any mobile offerings of N32. Though that may be due to the current market situation.

IMO, it likely has more to do with them being constrained with packaging/assembly than "scaling back operation." It would make sense for them to focus on MI300 due to the AI bubble.

I'd expect 7700XT to fill that gap rather soon.

AMD rep says RDNA3 lineup is now complete, they won't release any more SKUs.

This was at the pre-show press event, and Herkelmann didn't really say that 'refresh' versions similar to the RX 6x50 are ruled out:

There Will Be No More Radeon RX 7000 "RDNA 3" GPUs According To AMD But A Refresh Might Be On The Table

Talking during the pre-show of last night's Radeon Gaming event, Scott Herkelman (AMD's Senior Vice President) confirmed that their RDNA 3 portfolio featuring the Radeon RX 7000 GPU was now complete with the launch of the Radeon RX 7800 XT & RX 7700 XT GPUs. ...

Scott does mention that while the AMD RDNA 3 GPU lineup is complete and there won't be any additional SKUs, there might be future versions with similar specs and minor changes but that mostly depends on market demand and competition. This may be referring to a refresh similar to AMD's Radeon RX 50XT series which was introduced with the RDNA 2 GPUs, offering higher clock speeds and TBPs.

Herkelman didn't discard new graphics cards based on existing ASIC. ... Herkelman stated in the short interview that AMD may launch different versions, but the graphics cards aren't a new ASIC.

AMD RDNA 3 Lineup Concludes With RX 7800 XT, RX 7700 XT

The RDNA3 portfolio is complete, with no plans for a new ASIC.

www.tomshardware.com

Herkelman appeared on a panel during the AMD Gaming Festival livestream at Gamescom on Friday. When asked if the latest cards would “complete the RDNA 3 portfolio,” he answered, “The RDNA 3 portfolio is now complete. So of all products that we have planned to launch, that is, this is the last few products that we will launch.”

As always, more context is more helpful. Herkelman continued, “We may have some different versions, but they are not a new ASIC.” (ASIC means “Application-specific integrated circuit” — basically, a single chip design sold to suppliers.) So to break down a bit of this business jargon into more practical terms, Herkelman is saying that there are no new base-level chips planned to be added to the current Radeon 7000-series lineup...

What Herkelman did not say is, “There won’t be any new graphics cards based on the RDNA 3 chip design.” And anyone who’s familiar with AMD’s graphics card strategy over the last few years knows it. Based on the Radeon 6000 series, we can expect mid-generation upgrades — hypothetically cards titled RX 7750 XT, RX 7950 XT, et cetera — to be released twelve to eighteen months after the initial designs. These cards may have small boosts in clock speed, and perhaps other upgrades like extra RAM or an expanded memory bus, but still using the same underlying Navi 33, 32, and 31 chips at their core. It’s also not clear whether Herkelman was including Radeon laptop GPUs in his statement.

No, AMD Radeon did not say it's done making RDNA 3 GPUs

The death of any new AMD Radeon RX 7000-series graphics cards is greatly exaggerated.

AMD is not limited by wafer capacity, they are limited by packaging just like NVIDIA, or more than NVIDIA in fact, as NVIDIA controls the majority of CoWoS packaging at TSMC.

As a result, I don't think this is the real reason at all.

 

[Seanspeed]

Pretty sure there will be more RDNA3 parts, just not new chips.

We finally have a near perfect RDNA 2 vs RDNA 3 comparison courtesy of Computerbase.

Isn't this basically the same article posted in early August?

Die AMD Radeon RX 7900 GRE im Test

ComputerBase hat die Radeon RX 7900 GRE im Test. Sie zeigt eine Leistung auf dem Niveau der damaligen High-End-Grafikkarte RX 6950 XT.

www.computerbase.de

About the same as 6950XT on average.

Also it's not 'RDNA2 vs RDNA3', but rather 'RX 6950 vs RX 7900 GRE' which basically have the same specs - so it's reasonable to expect similar rasterisation and shader compute/raytracing performance:

Hardly surprising considering the exact same CU/TMU count and memory bandwidth, and very similar boost clock and GT/s fillrate.

Even in raytracing-heavy synthetic benchmarks like 3DMark Speedway, RX 6950 XT and RX 7900 GRE score about the same, while RX 7900 XT / XTX score 1.3 to 1.7 times higher, scaling with CU/TMU count, boost clocks, and memory bandwidth.

https://www.3dmark.com/compare/sw/122528/sw/758838/sw/300168/sw/550558/sw/209573/sw/306966
https://www.3dmark.com/compare/pr/2198884/pr/2485975/pr/2002278/pr/2044919/pr/2465595/pr/1948665

It's not like shader ALUs could gain superscalar out-of-order execution on these mild increases in transistor count per CU - so higher performance per CU is all about significanly higher frequencies, which didn't materialize with RDNA3, and dedicated fixed-function blocks for raytracing (BVH traversal), which didn't materialize either - though the latter should be expected to appear in RDNA4/5, if you consider these recent raytracing patents from AMD and Sony.

The 6800xt has been 500$ for over a year now. Most people interested in this performance level at that price would have already bought one.

RX 7800 XT should be on par with RX 6800 XT, and just a bit slower than RX 6900 XT / 6950 XT / 7900 GRE - even though it has less CUs and a lower texture fillrate in comparison to RX 6800 XT, there are higher clocks and memory bandwidth, and much higher Infinity Cache bandwidth and theoretical TFLOPS, because of dual-issue shader ALUs, and less power draw too.

So while ugrading to RX 7800 XT is not really worth it when you already have one of the above cards, for users of RX 5700 / 6700 / 7600 class cards or lower / earlier models (basically anything below RX 470/480, 570/580 and RX Vega/Radeon VII) RX 7800 XT should be at least 2x faster, and 1.5x faster than RX 6700 / 6750 XT; it also comes with 16 GBytes of video RAM comparing to mostly 8 GBytes on previous gen models.

Even though RX 7900 XTX could be further 50% faster in demanding games (ones with heavy raytracing requirements), it comes with 2x the price - so at $500, I think RX 7800 XT is very close to price levels that most people were expecting, and it's quite balanced as a brand new card for those looking to upgrade from an older model.

The 7800xt offers basically the same experience as the 6800xt which has been available at this price for over a year. There is no market for this card that wouldn’t have already bought a 6800xt. It’s hardly more power efficient at a meager 10% reduction.

Does that mean that AL+ is not open source and doesn't even have a public SDK?
Edit: TIL Anti-Lag+ is a profile basis, driver-side function unlike Reflex.
