Emulating Double Precision on the GPU to Render Large Worlds in #GodotEngine

Graphics engineer found that Portal RTX isn't actually limited by Raytracing in general even on Radeon 6000 cards. So, if you guessed that the game's performance is a joke – you were right!

Instead, the game is ridiculously poorly optimized in totally different areas, so it's low performance on any GPU is kinda intentional:

There's a huge ubershader, that somehow makes way too many operations outside Raytracing pipeline. It is either a system-wise driver bug in general or API bug.

AMD announced Ryzen Z1 and Z1 Extreme for Windows and Linux gaming handhelds. AMD says the Z1 and Z1 Extreme are temporarily exclusive to Asus (ROG Ally) but that we may see other partners in the future with these or future Z chips.

It seems, that Extreme will be almost as powerful as PlayStation 5 and Xbox Series X. So, it will be significantly faster than Steam Deck and recent models from GPD, OneX, and AYA, but the chip is still limited to 30W TDP and the limit is keeping it behind real PS5 performance.

#AMD announced FSR 3 with better consistency and frame generation:

#Hardware #GPU

It's #OpenSource under MIT License and frame generation will be supported by Radeon 5700 and newer and RTX 20 and 30 series cards, unlike NVIDIA equivalent with only RTX 40 in mind.

Upscaling without generated frames will work on RX590 and GTX 10. And the implementation is promised to be easier than FSR2. MIT repository will be available next year.

VRAM is essential for games and Hardware Unboxed measured how:

🔥 Deadlock just saved my GPU kinda (and this may also help you)

The game made my PC go nuts every few minutes — some fans were blowing at max speed and I thought it's CPU, since GPU can't overheat at 70, right? Wrong!

So I opened up Afterburner to use temps overlay: around 70 on both CPU and GPU, nothing unexpected. Instead, I decided to check GPU-Z that has GPU Hot Spot which was… 105C, over 30 degrees higher than on average, on 3060 Ti with three fans. Not what I expected!

Took the cooler off, thermal compound was solid and dried out completely. Cleaned up, repasted into MX4, now the Hot Spot is only 85 while the average is about 60-65.

Which means: if Deadlock makes your PC go crazy in terms of fan speed, check both CPU and GPU, and check it with utilities that can see Hot Spot, since average can be fine. Valve know how to utilize every molecule of your GPU and it will heat it up.

Finally, enough VRAM for Unreal Engine 5 games! #Hardware #GPU #NVIDIA #meme #UE5

Wow: #NVIDIA secretly replaced 3050 8GB with 3050 6GB... and it's actually an absolutely different card!

(Yep, it's much worse)

And it could be an amazing offer for ultra budget PC or office prebuilt upgrade. But it's not 3050: it should be named and priced differently.

Here's how much VRAM you need for modern gaming!

I know, you like #GlobalIllumination and all the abbreviations it caused: RTGI, SDFGI, or HDDAGI, but here is yet another one on Radiance Cascades:

Rumored specs of the upcoming #NVIDIA graphics cards. They will be even more power hungry and 5070 is still going to have 12GB VRAM (which is clearly not enough even for QHD).

5090 is gonna be insanely fast if specs are correct. With such power it will be in huge demand for professional users and businesses. Forget the MSRP: AI bros and Hollywood studios will buy them out for x2, no doubt.

Yet another new year surprise: the retail version of Intel B580, that was initially sold out in its first day, suffers from driver overhead.

The card works horribly bad with older CPUs, not because it has to, but because there's something terribly wrong on a driver level.

They also confirmed all rumors about the most powerful APU lineup: up to 40 units on GPU and up to 120W TDP for it. Leaked benchmarks outperform RTX 3060 desktop.

The flagship 40CU GPU is using system RAM, but can allocate up to 96GB of it. Which may help with VRAM demanding games and tasks, like AI and simulations. Usually, AMD allows you to allocate up to 50% of RAM on compatible devices.

Here are some numbers: Shader Cores performance hasn't changed since the previous generation. Which means, that these cards will only show a noticeable boost with Frame Generation.

Meanwhile, a laptop 4070 in its most simple 65W TDP variant, lost to the new flagship integrated graphics from Radeon. It will appear later this year in NUC boxes and premium laptops.

This Radeon 8060 is integrated into the CPU and can utilize up to 96GB of system memory. It's like a console graphics on steroids. But still with reasonable TDP of 45-120W.
