Did I miss something or was it never mentioned that PowerVR's whole thing for the past like 20 years has been that their GPUs used Tile-based Deferred Rendering? For people who don't know. PowerVR, like Adreno and Mali GPUs, is a tile-based GPU. What that means is that they break the frame into tiles and send each tile to a cluster of ALUs to rendered within a small amount of extremely fast, extremely low-latency on-chip memory. You can think of it as a bunch of mini-GPUs with their own memory all working on a chunk of the frame. This allows the image to be drawn without having to access external memory to update the different geometry buffers. Each architecture uses different sized tiles and works slightly differently but each have the same benefit, not being as bound by external memory speeds. The speed on these on-chip memory pools also increase with GPU clock speed. So if thing are well optimized for tile-based rendering and external memory isn't used for much more than tile list and textures, a tile-based GPU can go from rendering something at 720p to 1080p just by clocking it 2.25x higher. With immediate mode renderers like Nvidia and AMD, an increase in resolution would also require in increase in external memory speed. PowerVR does something a little differently than Adreno and Mali though. It has a Tile-based DEFERRED renderer which means it does Hidden Surface Removal (HSR) on-chip and defers any texture or fragment shading until that won't ultimately be drawn over later on in the frame. This can save a huge amount of processing resources and bandwidth for forward rendered games. Other architectures can also insure that the GPU doesn't shade obscured pixels but it requires the program's developer to sort polygons from near to far or do a depth pre-pass, the latter of which requires all polygons to be rendered twice. The fact that HSR does this automatically with opaque geometry means that you can instead sort by material to cut down on texture reads. HSR doesn't work on opaque geometry though so it would have a similar loss in efficiency that other architectures would.

I remember PowerVR 3D accelerators for PC from around 1997, rivaling the 3Dfx Voodoo, Matrox and Nvidia Riva cards. Apparently PowerVR was also used as the GPU for the Sega Dreamcast.

Gary, You need to do a video on nvidia's cuda cores.

I remember that the Galaxy S4 Exynos version had a PowerVR GPU in it.

I just skip everything when I see a notification from Garry explains!!!

Thanks Gary I really needed this;)

Literally asked about powerVR on your last video. Thank you for making the video.

Awesome video Gary! Please try and do a speed test g on one of the phones with powervr gpu!

Wow, thank you Gary, I did not have much knowledge about the Imaginations' PowerVR GPUs other than knowing their relationship with Apple

Hello, Nice vídeo.. gary i'm still waiting for video on MIPS cpu.. and MIPS vs ARM...🙃

In 2014 I use midrange Lenovo with PowerVR gpu. The graphics so smooth like butter.

Sir please make a video on gpu's in apple's latest soc's like a12 bionic.

What is the Adreno equivalent GPU for the PowerVR GM9446 found in the Helio P90?

*GARY!!!* *Good Morning Professor!* *Good Morning Fellow Classmates!*

Can you do a video on GPU architecture / if one exist , link to some deep dive reading on that subject ? I've been looking for such info for quite some time [ Thanks , ece students around the world]

Hi gary, so is it right to say powervr 9446 is a gd gpu comparable to adreno 612 or 616. Based on your video explanation of the numbers powervr 9446 is 4*64 shader *970mhz which is around 248.32gflops ?

Gary can you make a video about how save is newer version of Android agaist apps with explits? Is still Android vulnerable on vulnerabilities? Thanks

Great video, Gary. I still use an iPhone 6S with the A9 SoC and Power VR 7600GTX inside it. Do you know what the computational power of the 7600 is in GFLOPS? Or is this decided by the A9’s CPU?

If MediaTek would've used a more powerful version of the PowerVR GPU in the Helio X30 SOC then IMG PowerVR might have got some more recognition. Though, the fully customized IMG PowerVR 7XTP-MT4 @ 850MHz (PowerVR GE7400) was equal to the PowerVR GT7600 that was in the A9 Apple SOC and was on par with the SD820's Adreno 530. Not to shabby and PowerVR's GPU's never throttle. its peak performance stays put and can sustain it's clock frequencies. That I like. There are reviews of the Meizu 7 Pro which use the 10core Helio X30 with the PowerVR 7XTP-MT4 and it ran cool and sustained full clock frequencies on both the GPU and CPU. I was going to buy the 7 Pro but it didn't have the radio (BANDS) I needed. Plus I already had the LG v20 which had the Adreno 530. Though, I had to mod the thermal.conf. file just to get the phone to quit throttling at low temps and causing nauseating in game hitches. So iave a fully unlocked Adreno 530 with an extra 10% performance gain from a forced Vulkan driver update thanks to XDA devs. But, no one should have to mod there phones data files or the phone itself just to have stutter free gaming or any kind of media consumption. Also I did have to replace the thermal paste inside the phone as well. Being the LG v20 is the last true high-end smartphone with a removable battery, it wasn't to hard, opening up the phone. If IMG comes up with another GT7600 type great GPU, I would def. consider it. Remember the Apple iPhone 6s and how much better the games looked and played on that GPU than others at that time. it was unmatched. They had a edge with the metal API but' now Vulkan is mainstream, so a Adroid based phone with a IMG PowerVR GPU can have those great looking GFX and the sustained peak performance.

PS classic has the ge8100. Helio A22 has the 8320 and can handle reicast with a breeze as well as h265 10bit in sw mode.

Great info

Nice Video .Thank You

It was in the Dreamcast too

Love this... Can you do a Nvidia arm processor deep dive

Surprised Samsung didn't buy PowerVR after apple dumped them. ARM Mali is way behind andreno and the new apple gpus

I remember power vr being really good back in the day

So how does Power VR stack up against other GPUs like the adreno and mali. Also tell us about the gpu Apple uses now

Sir make a comparison video for adreno and apple gpu

My first Android had power Vr, back in 2011

Hi garry, could you explain about sensor available in our smartphone? Thanks garry

The MediaTek Helio X30 (10 core CPU) has a PowerVR GT7400plus (IMG PowerVR 7XTP-MT4 @ 850MHz 128ALU's) which is like a mid range GPU but the greatest thing about it, is that it sustains it's peak GFlops with no throttling. A Snapdragon 820's Adreno 530 has 256 ALU's, kind of like the NVIDIA TV Sheilds Maxwell based Tegra X1 has 256 cuda cores (ALU's) and is about equal the PowerVR GT7600 that gary mentioned, and was in the iPhone 6s. though it only has 192ALU's. so you cant compare GPU GFlops just by how many ALU's it has.

Had an Asus gen 1 phone with intel atom and power vr GPU , it was capable of handling games in full HD in 2014 itself

I know it isn't but why I get an illusion of voice and image are not in sync

If itwas pawer vr ge 8100 so it has 0 alus?

so whats is the best and most efficient, Adreno or PowerVR? who is the king? I heard that Adreno is x2 more power efficient than Mali, for example. Generally Adreno is considered superior among mobile graphics, is that true Mr. Gary?

Apple actually learned from Imagination on how to make powerful hardware without boasting big numbers, reason why Apple switched thier soc division and tried to show the world that Apple designs it's own hardware despite still needing blueprint from Arm and Imagination till date.

didn't exynos version of the samsung galaxy s3 or s4 use powerVR?

DreamCast had PowerVR... If im not mistaken, other consoles sport powervr gpus in the 90s

It would be great if they made a discrete GPU

*My takeaways:* 1. Different companies use different name scheme for their GPU "cores" 7:21

the heilo x10 has powerVR rogue G6200 so it has zero 16bit floating point operations per clock cycle? Thats weird

So Apple funnily enough has the equivalent of architecture license from Imagination currently, since as per multiple sources their mobile GPU architecture is heavily based on underlying PowerVR patents and tech

They had it coming, when they provided GPUs for Android SoCs their drivers were crap and resulted in terrible performance

" assuming the new generation is better than the last" Bold of you to assume my good man.

So where does power VR stand against adreuno GPUs?

So lets see, PowerVR Rogue GE8320 inside the Mediatek Helio P22 of my Samsung device is a dual cluster GPU so 2. It contains 4 pixels per clock so core config is 2/4 or 64/128 SIMD. And is clocked at 650MHz. That means 64 FP32 FLOPS/Clock or 128 FP16 FLOPS/Clock. So 64* 650MHz(0.65) = 41.6 GFLOPS or 128*0.65 = 83.2 GFLOPS.

Wow. Now that's called TMI.

I think the first S series phone came with a power vr gpu

What is more efficient Mali or PVR GPU

I wonder when will real time ray tracing reach mobile. 2030 for a mobile gpu matching a 2080?

Dreamcast had a PowerVR2 gpu but its far surpassed by newer chips

asus Zenfone 2 series had powervr gpu

wait, that car... I think I just saw it 15 minutes ago.

Hmmpp What phone will get a new PowerVr in 2020 hope it come from the Android.

I still use my iPad 4 that has a PowerVR GPU...

You listened

Do this kind of mobile gpu video for all brands like nvidea, adreno, mali, powervr. No one explains about mobile gpu in Internet.

They are using the wizard architecture.

Doesn't Qualcomm have the best GPU on the market with their Adreno range?

How does this person know so much about the internal stuff about Imagination Technologies?

my redmi 6 had powervr gpu

Samsung also used them before mali

sooo 4 is 2.000.000.000 pixels per second! phew

*INTEL HD GRAPHICS LEFT THE CHAT*

I have p90x

Power vr iphone 5s

Apple and imagination didnt go seperate ways.. Apple bought it(most of it) Apple's gpus in their current chips are essentially powrvr gpus..modified Same way qualcomm modifies arm cpus into kryos

However Gary, PowerVR gpu in helio x10, helio p22 and Helio a22, all of em used PowerVR GE83XX, which was already 5 years old to date, just researched it :) That's why they sucked in 3D gaming

Mali has Approximately 300Gfops Adreno has over 600Gfops But the deference in performance . Is less than 10 - 20 % Compare to Adreno have double the computing power . Why that happened I see that between Nvidia and AMD . AMD GPU have a lot of computing power . But these cards fail to translate that computational power into something practical . I asking for expert

SEGA Dreamcast

My brain crash after watching this

Maybe a few new horses in the console market might nail compiling to native. with triple c (c compilable script plus language extensions, c or c++ and assembly including both parallel and serial compute threads. As close to full native as possible but program mostly architecture independent pasm leading to Vulcan compute and inferencing base image generation plus xess image upscaling and frame upscaling on arm.

stereotype : Adreno is best 😃

Second 😋

1st one again!

We only know they are weak and expensive
