Multicore or Multi-pipe GPUs: Easy steps to becoming multi-frag-gasmic

Posted by Ed Plowman,

The ARM Mali-400 MP was the world’s first embedded multicore graphics processor (GPU) when it was launched, back in 2008, and Mali-T604 continues that trend. Since then, there have been a number of new GPUs claiming to be multicore and people have asked me lots of questions seeking to quantify what is a “core” versus a “pipeline” and about scalability, so I thought I’d share the answers with a wider audience. My colleague Jem Davies has noted before in his blog that the beginning of wisdom is to call things by their correct names. Graphics can sometimes be a very confusin...

Game developers head off from GDC to create the next wave of exciting content

Things have now wound down at the Moscone Center after a week of the Game Developers Conference (GDC). We’ve been catching up on what’s new, what’s cool and who’s who in the world of gaming, and after a hectic five days we’ve packed our bags and headed home.

It was a busy week, but what were the highlights? Well, for us at ARM, the rise of stereoscopic gaming was a hot topic and with our own Stereoscopic Space Racer game ‘TrueForce’ on show, we were really encouraged to see that.

The developments around gaming engines also caught our eye. Scaleform were showing their custom engine for rendering flash effectively on the GPU – it really works, it’s fast, and it makes the creation of UIs for games, in addition to UIs for applets, really easy.

The guys from Unity were also here in force, with their game engine now enabling developers to easi...

Mobile Game Graphics Going High-End

Consumers are now looking for handsets that deliver everything that previously required separate devices, including high-end 3D gaming. Until now the meaning of ‘high-end mobile 3D graphics’ has mostly been limited to good looking static models with baked light maps. When can we expect to see some proper real-time pixel toasting?

Excitingly enough, a few pioneering game developers have lately created some mobile content that tries to do something beyond the basic fixed function shading which we all grew sick of in the 90’s. Rage by Id pushes the bar of OpenGL ES 1.1 using Carmack’s black magic texture streaming tricks. Infinity Blade, based on the Unreal Engine, features some basic per pixel bump shading the low resolution versions for iPhone. In the higher resolutions however, the game seemingly is more or less surviving on the great artist work alone.

ARM’s GPU strategy has always focused on high performance in the demanding pixel shading cases, required to truly enable desktop- and console-leve...

Triangles Per Second 2: A Chocolate Teapot of a Graphics Benchmark

In the first blog of this series, I claimed that as a GPU performance metric, triangles per second (aka TPS or triangle rate) is a chocolate teapot – i.e. utterly and completely useless – and talked about the difficulty of getting a consistent definition of the metric. (Without such a definition, you can’t compare triangle rate numbers from different vendors.) I also gave some technical background on how GPUs draw triangles. In this installment, I’ll talk about how GPU vendors exploit the definition problem to claim enormous triangle rates, while actually telling you nothing about the performance of the GPU. Finally, I’ll explain why, even if you were able to measure an honest triangle rate, you wouldn’t want to.

How to draw a gazillion triangles per second
OK, so you’re a struggling GPU vendor who wants to claim “N gazillion triangles per second”. It doesn’t m...

Enjoying gaming…at last!

With the Game Developers Conference happening this week, I got to thinking about how gaming is becoming so much a part of all of our lives. I’m not sure if I dare say it amongst my gaming obsessed colleagues(!), but I’ve never really been one for games – whether it was board games or video games. My memory of gaming as a child was waiting and waiting til my two brothers would finally say “OK, it’s your go” and hand me the joystick, then within a matter of moments and probably flying a spaceship or suchlike in the wrong direction, I was dead, back to the end of the queue while they seemed to take forever to lose their lives! Not fun!!

But gaming is becoming so much more pervasive now, and it is effortlessly breaking through to so many demographic groups that wouldn’t have typically engaged in gaming. It only took my Mum a few moments to get the hang of Angry Birds on my ARM® Mali GPU-enabled tablet, and my stepdaughter is only interested in me for my smartphone so she can play Teeter! The simplest of game concepts seem to be so universally effective.
