iPad 2 : Some Definitive GPU Benchmarks…

This is the first definitive set of GPU benchmarking for the iPad 2, courtesy of AnandTech…

Developers with existing titles on the iPad could conceivably triple geometry complexity with no impact on performance on the iPad 2.

With a lit triangle, a simple test for fragment shader performance…

While the PowerVR SGX 535 in the A4 could barely break 4 million triangles per second in this test, the PowerVR SGX 543MP2 in the A5 manages just under 20 million.

Texture fetch…

5x increase in texture fetch performance. This has to be due to more than an increase in the amount of texturing hardware. An improvement in throughput? Increase in memory bandwidth? It’s tough to say without knowing more at this point.

Those of us working with multiple FBOs for post processing effects, should be very pleased with both the increase in fragment shader performance and the apparent increase in texture fetch throughput.

GLBenchmark 2.0 app & Infinity Blade tests…

While we weren’t able to reach the 9x figure claimed by Apple (I’m not sure that you’ll ever see 9x running real game code), a range of 3 – 7x in GLBenchmark 2.0 is more reasonable. In practice I’d expect something less than 5x but that’s nothing to complain about.

There are more in depth details in the full article, and they promise follow ups.

But for a simple head to head comparison running GLBenchmark 2.0 Egypt…

Apple iPad 2 (1024 x 768) : 44 FPS

Motorola Xoom (1280 x 800) : 11.8 FPS

Apple iPad (1024 x 768) : 8.1 FPS

Tech Focus : Killzone 3

Digital Foundry talks with Guerrilla Games’ technical director Michiel van der Leeuw about the development of Sony’s latest first person shooter, Killzone 3.

One of the things we’re very proud of is one that nobody sees: We’re doing a full depth rasterisation of tens of thousands of triangles in a software rasteriser on SPUs so we can do occlusion culling against it. This allows us to do much more aggressive culling, which in the end allows us to do more complex scenes and further draw distance.

With MLAA we reduced our load on the RSX quite a bit, we halved the size of the G-buffers and some depth/stencil re-primes between passes were no longer necessary, which gave us additional speed boosts. In the end it gave us quite a bit of RSX cycles and memory back, which we invested back into texture streaming, draw distance, texture sampling quality and – more indirectly – the variety in characters, environments and so on.

We were already doing most of our post process effects on the SPUs, but with MLAA moving to SPUs as well we had the entire post chain running there.

The whole article is full of fascinating little bits of insight into how Killzone 3 ticks under the hood.

If you’re not already doing, or at least looking at doing the things mentioned in this article, and you’re working on the PS3, then you are behind the times.

Apple Now Number One In Global PC Sales*

Surging iPad shipments have propelled Apple to a 17.2% share of worldwide mobile PC shipments in Q4’10, placing Apple at the top of the DisplaySearch market share ranking. According to preliminary results from the DisplaySearch Quarterly Mobile PC Shipment and Forecast Report, Apple shipped more than 10.2 million notebook and tablet PCs combined, nearly a million more units than HP in Q4’10. While Apple’s iPad is benefiting from a first-mover advantage, particularly in mature markets, its notebook PC shipment growth rate continues to exceed the industry average.

Rank Brand Units Share
1 Apple* 10.2 17.2%
2 HP 9.3 15.6%
3 Acer Group 8.4 14.0%
4 Dell 5.9 9.9%
5 Toshiba 5.1 8.6%

*Including iPads.

California’s SB 1411 Internet Impersonation Law…

California’s SB 1411, which adds a layer of criminal and civil penalties for certain online impersonations, goes into effect starting today. The consequences include a fine of up to $1,000, and/ or up to a year in jail.

THE PEOPLE OF THE STATE OF CALIFORNIA DO ENACT AS FOLLOWS:

SECTION 1. Section 528.5 is added to the Penal Code, to read:
528.5. (a) Notwithstanding any other provision of law, any person
who knowingly and without consent credibly impersonates another
actual person through or on an Internet Web site or by other
electronic means for purposes of harming, intimidating, threatening,
or defrauding another person is guilty of a public offense punishable
pursuant to subdivision (d).
(b) For purposes of this section, an impersonation is credible if
another person would reasonably believe, or did reasonably believe,
that the defendant was or is the person who was impersonated.
(c) For purposes of this section, “electronic means” shall include
opening an e-mail account or an account or profile on a social
networking Internet Web site in another person’s name.
(d) A violation of subdivision (a) is punishable by a fine not
exceeding one thousand dollars ($1,000), or by imprisonment in a
county jail not exceeding one year, or by both that fine and
imprisonment.

I wonder if the majority of Californian’s actually support this? If not, and bearing in mind how wacky US law is at times, I wonder if a case could be brought against the makers of the bill by “THE PEOPLE OF CALIFORNIA” for impersonating them without their consent?

One positive upshot of this law, I guess, is that we’ll get to see which celebrities and moguls have a sense of humour and which don’t.

“The Wall Street Pentagon Papers”

I understand the importance of the new WikiLeaks documents. However, we must not let them distract us from the new information the Federal Reserve was forced to release. Even if WikiLeaks reveals documents from inside a large American bank, as huge as that could be, it will most likely pale in comparison to what we just found out from the one-time peek we got into the inner-workings of the Federal Reserve. This is the Wall Street equivalent of the Pentagon Papers.

We were finally granted the honor and privilege of finding out the specifics, a limited one-time Federal Reserve view, of a secret taxpayer funded “backdoor bailout” by a small group of unelected bankers. This data release reveals “emergency lending programs” that doled out $12.3 TRILLION in taxpayer money – $3.3 trillion in liquidity, $9 trillion in “other financial arrangements.”

I’ve been arguing for years that the market is rigged and that the major Wall Street firms are elaborate Ponzi schemes, as have many other people who built their beliefs on rational thought, reasoned logic and evidence. We already came to this conclusion by doing the research and connecting the dots. But now, even our strongest skeptics and the most ardent Wall Street supporters have it all laid out in front of them, on FEDERAL RESERVE SPREADSHEETS.

Do you get that? The very people most responsible for crashing the system, were then rewarded with trillions of our dollars. This gave that select group of insiders unlimited power to seize control of assets and have unprecedented leverage over almost everything within their economies – crony capitalism on steroids.

Insane!

Let me sum it up for you: The American Dream is O-V-E-R.

Welcome to the neo-feudal-fascist state.

People throughout the world who keep using the dollar are either A) Part of the scam; B) Oblivious to reality; C) Believe that US military power will be able to maintain the value of an otherwise worthless currency; D) All of the above.

No matter which way you look at it, we are all in serious trouble!

You should read the whole article.

iPhone Inc. : A $200B Business Ranked 10th in the World

Assume Apple (AAPL) today is worth $391 billion (nearly 40% more than its current market cap), as the analysts at Trefis estimate it to be.

Assume as well, as they do, that the iPhone represents 53.5% of that value.

Then it follows, according to them, that the iPhone, were Steve Jobs to spin it off as a separate company, would be worth $209 billion.

How does that compare with the largest companies in, say, the automotive industry, or pharmaceuticals, or media?

It would dwarf them all. In fact, team Trefis could find only ten companies on the planet — three of them Chinese — that are more valuable than the iPhone. They are

  • AT&T (T): worth $224 billion in Trefis’ valuation
  • Petro China (energy): $225 billion
  • China Construction Bank (banking): $229 billion
  • IBM (IBM): $234 billion
  • BHP (mining): $236 billion
  • Proctor & Gamble (PG): $243 billion
  • Microsoft (MSFT): $262 billion
  • ICBC (banking) : $265 billion
  • Exxon Mobil (XOM): $349 billion
  • and, of course, Apple itself: $391 billion

I can’t see Apple forming two separate companies, simply because the entire company is moving towards iOS, rather than OS X and iOS diverging.

But it would make for an interesting share split.

How Big is iOS as a Gaming Platform?

iOS has nearly three times more games than the previous twenty-five years of gaming combined.

From TUAW.

Just how many of those 40 – 50,000 games are straight ports, rip-offs or dodgy emulations of earlier games? Or even rip-offs of other rip-offs? A lot in my opinion, and also my personal experience. One thing we can be sure of from these figures is that innovation, whilst definitely a factor in the App Store, is not the driving force.

NOTE : [iOS] has a total of 51,856 games listed (note that the 42,007 figure I have used is only active games, whereas TouchArcade has an all-time count that includes titles that are no longer available for download) and they report that 12,876 have the word “lite” in the title, with a further 6,542 having the word “free”. If we assume these are demo versions of games that are also available for purchase, and therefore eliminate them, we arrive at a total of 32,438 games on the App Store — still well in excess of the total across the games consoles.

“Facebook Could Beat Google to Win the Net”

Facebook gets so many page views that it now serves up an astounding 23% of the U.S.’s online display ads.

[T]here’s so much interaction and information being shared inside Facebook that it has become a decent-sized replica of the Web inside the Web.

Anyone remember AOL?

Singels article is worth a read, even if you don’t see things from his perspective, or agree with the conclusions he draws.

Qualcomm buys “soft radio firm” Sandbridge

Qualcomm, the firm most commonly associated with the Snapdragon platform that powers many Google Android devices and literally every Windows Phone 7 device, is rumored to have spent $55 billion acquiring New York based Sandbridge Technologies. They specialize in what’s known as “software defined radios”, or in plain English: they make processors that can connect to a cellular network that uses one type of technology, say GSM, then when it wants to support something totally different, like CDMA, it can just by shifting a few bits around.

This is exactly what Apple want to do with future iPhones.

Why exactly would Qualcomm keep this a secret? It’s unknown, but Sandbridge’s website is down so something is definitely up.

I think this may be quite significant, and linked to the Qualcomm / Apple rumours from September. After Intel purchased Infineon’s wireless unit earlier this year there was some speculation about whether Apple would jump ship to Qualcomm for radio chips which could cover CDMA requirements.

If Qualcomm have the lead on software radios then Apple may well already have made its decision.
