Nvidia responds: There’s cash in CUDA

Thursday, October 1st, 2009

Some companies take a very laid back approach to the press. I could publicly allege that Itanium was a front for a money-laundering operation and I doubt I’d hear a peep of complaint from Intel.

Actually, that might explain a lot. But I digress.

The point is that Nvidia, unlike Intel, is acutely tuned in to what people are saying about it — and can be quick to respond. (more…)

Reports of CUDA’s death exaggerated?

Wednesday, September 30th, 2009

In my last post I suggested that DirectX 11’s extensive GPGPU support could mark the end of the road for CUDA. And I do expect that mass market GPU applications will quickly move to DirectX rather than restricting themselves to a single architecture.

But the other day I was discussing DX11 with Bit-Tech editor Tim Smalley, and I found him very reluctant to write CUDA off just yet. He pointed out that CUDA retains one big advantage over DX11, in that developers can knock up CUDA routines directly in C – or Fortran or even Matlab – without having to deal with the DirectX API.

All eyes on Nvidia as GTC kicks off

Wednesday, September 30th, 2009

After last week’s Intel Developer Forum, it’s now Nvidia’s turn. Later on today the company will open its three-day GPU Technology Conference in San Jose – a more formal affair than last year’s flashy “Nvision” expo, but still a high-profile international event, and one which yours truly is lucky enough to be attending.

(The picture, in case you’re wondering, is a strange engine-type affair that’s been set up at the entrance to the delegates’ hotel, apparently to welcome us as we arrive. I guess that’s how they communicate with one another down here in the Valley.) (more…)

Nvidia Ion netbooks: first look

Tuesday, September 15th, 2009

The first Ion-based netbooks are beginning to trickle in, so yesterday Nvidia took the opportunity to introduce the technology to us formally. And if there was any doubt as to the focus of the demo, it was quickly made clear by the presence of a gigantic 1080p Sharp Aquos TV with a tiny netbook attached.

The netbook in question was HP’s Mini 311, announced today, and it offers a very similar core spec to others we’ve already seen from the likes of Samsung. The usual 1.6GHz Atom N270 and 2GB of RAM are joined by an 11.6in 1,366 x 768 LED screen and that shiny new Nvidia Ion GPU, which also allows manufacturers to include an HDMI port for hooking up to an HD TV. The Mini 311 is pencilled in for a £349 launch price, which is actually a rather competitive price for its size and spec. (more…)

Will Nvidia PhysX ever be worthwhile?

Tuesday, June 30th, 2009

Nvidia has talked up its PhysX system incessantly since it bought Ageia Technologies, creator of the engine, in February 2008, but it’s struggled to make a significant impact on the PC gaming landscape. So, despite the impressive tech demos and endless optimism, is PhysX looking more like a white elephant with every passing GPU and game release?

Hands on with Nvidia Tegra

Friday, June 19th, 2009

Nvidia’s Tegra was first introduced in June 2008, touted as a “computer on a chip” that would saunter into numerous types of device – most notably MIDs – and beat Intel’s Atom at its own game. It’s been all quiet on the Tegra front since, but we’ve finally had the chance to go hands on with Nvidia’s exciting new technology.

The ARM11 core (which is also used in the Zune, several Nokia phones and the HTC Dream) is the main processor but, for tasks that have specialist demands, several other chips are included: a GPU handles gaming and 3D tasks, an audio unit is optimised for mp3 and radio playback, a 2D graphics chip can handle a camera.

Separate chips tackle video encoding and decoding, with Nvidia promising the ability to encode and decode 720p video simultaneously. The board also houses flash and system memory, which are the larger chips towards the bottom of the PCB.

First look: the Ion-powered Lenovo Ideapad S12

Thursday, June 18th, 2009

Lenovo’s Ideapad S12 is one of the first netbooks we’ve seen to use Nvidia’s Ion platform, which can allegedly “turn a netbook into a notebook” thanks to its combination of Intel Atom CPU and Nvidia GeForce 9400M GPU.

It’s a new part that’s only been used by Acer up until now, in its netbooks and A-Listed Aspire Revo R3600.

That ambitious claim comes courtesy of Matt Wuebbling, a senior manager in Nvidia’s notebook division, who’ll understandably talk up the chances of his own product in the face of endless scepticism. However, having been hands-on with Lenovo’s latest offering and seeing the Ion in action, we’ve seen plenty of evidence to support his claims.

All the week’s reviews

Friday, January 9th, 2009

Christmas came and went, New Year flew past with a bang but PC Pro’s reviews kept on coming. We’ve much catching up to do with this week’s round-up, so we’ll keep the focus on the most notable of the twenty-plus reviews since the festive period.

New Year’s entertainment

We got unfeasibly possessive over a little media player in the Labs, thanks to the fabulous AMOLED screen on Cowon’s S9. It shared so many strengths with the iPod Touch, but with its individually lit pixels – no backlight required – it breathed new life into those iPlayer programmes we’d saved over Christmas. A truly stunning screen and a very nice little device.

On the subject of screens, the oddly named Village Tronic ViBook arrived to extend the life of our old office TFTs. It attaches to the back and converts any display to work over DisplayLink – essentially USB – to run multiple monitors without the need for multiple video outputs. Will 2009 be the year of DisplayLink?

Can Nvidia halt its current decline?

Wednesday, December 17th, 2008

This month in the Labs we’ve mostly been testing graphics cards, and you’ll be able to read the results when the next issue of Pro is published in January. But I don’t think I’m giving too much away by revealing it’s not particularly happy reading for Nvidia.

Put simply, Nvidia’s desktop department is having a torrid time of it right now: when its own chipsets aren’t faulty they’re generally slower than ATI’s; and when they’re not faulty or slower than ATI’s, they are dearer, which negates any advantage they might have had.

It’s a cyclical thing. ATI had its troubled times before the HD 3000 cards arrived, and when new technology arrives the situation may well reverse again. But for evidence of where the strength lies you should alway look to the board partners – and it’s a one-way surge right now.

Nvidia keeps failing the name game

Friday, September 26th, 2008

At present it’s nothing more than an industry rumour, but it’s one that can’t come true soon enough. Nvidia is reportedly about to rebrand its graphics cards in a quest for much-needed simplicity.

Gone will be the 8000 and 9000 number schemes, with things going back to (kind of) the beginning. So we’ll see 100s and 200s, and all the divisions of ten in between; while the suffix letters will find their way to the beginning of the names, a la G100 and GT140.

Because that’s simple.

Perhaps I’m just being picky on a Friday afternoon, but surely I’m not alone in thinking simple would have been to do away with the ghastly prefix/suffix convention altogether, in an entirely fresh start. Can anyone even remember why a GT was decided to be faster than a GS, which in turn is faster than a G, in the first place? (more…)
