Assassins bemoan poor console chip performance

Posted on October 10, 2014 by - News

assassins-creedAssassin’s Creed Unity senior producer Vincent Pontbriand has waded into AMD’s console performance saying that his new game’s 900p frame rate and 30 fps target on consoles is a result of weak CPU performance.

He said that while the GPUs on the machines are really powerful and the graphics look good, the game was technically CPU-bound and the CPU has to process the AI, the number of NPCs we have on screen. All these systems running in parallel.

Speaking to Hot Hardware, Pontbriand  said game designers were quickly bottlenecked and it was a bit frustrating.

“We thought that this was going to be a tenfold improvement over everything AI-wise, and we realised it was going to be pretty hard. It’s not the number of polygons that affect the framerate. We could be running at 100fps if it was just graphics, but because of AI, we’re still limited to 30 frames per second,” he said.

The comments are being seen as damning AMD’s APU. The Jaguar CPU inside both the Sony PS4 and Xbox One has a relatively low clock speed and, while both consoles may offer eight threads on paper, but it appears that games can’t access them.

Pontbriand said that one thread is reserved for the OS and several more cores will be used for processing the 3D pipeline. Between the two, Ubisoft may have only had 4-5 cores for AI and other calculations. This means that the performance is about the same as the last generation of Xbox 360 and PS3 CPUs.  In fact these were clocked much faster than the 1.6 / 1.73GHz frequencies of their replacements.

To be fair it is hardly AMD’s fault. Microsoft or Sony could’ve specced out a variant of the core clocked at 2-2.4GHz and boosted total CPU throughput, but they didn’t. The programmable nature of the GCN architecture inside the Xbone and PS4 is meant to compensate for the relatively lightweight core, but AI calculations may simply be beyond this.  GPU calculations tend to be high latency, and AI typically requires fast response times.

Sony bemused at PS4 success

Posted on August 20, 2014 by - News

PS4Even the marketing people at Sony can’t work out why its PS4 is selling so well.

Sony is cleaning Microsoft’s clock in the console wars despite the fact that the two products are pretty much the same spec with the same price.

It has sold more than 10 million PS4 consoles have been sold in the nine months since launch. It’s a bigger number than anyone anticipated, and even  the president of Sony’s Worldwide Studios, Shuhei Yoshida, doesn’t know why.

He was a bit nervous because he did not completely understand what’s happening. Sony has had marketing people look into this early success, and have found that a lot of PS4 owners did not own a PS3, or any last-gen console at all.

He said that normally when you see a great sales number, instinct tells us we should be concerned about future sales. If Sony sold this number of units at this stage in the game there would be no more consumers it can sell to in the future.

It seems that is not the case and a lot of the PS4s are being flogged to those who have never owned one of Sony’s consoles in the past.

It does not answer the question why, but according to our nephew it is because the Xbox does not have as many good games as the PS4 yet.

Console shipments to rebound this year

Posted on October 4, 2013 by - News

gamer-sexWith the imminent rollout of Sony’s PlayStation 4 and Microsoft’s Xbox 360, we didn’t exactly need serious research to conclude that console shipments would go up this year, but thanks to the IDC, we’ve got a few figures, too.

IDC predicts console shipments in 2013 will be “marginally higher” than the 2012 total of approximately 33 million units. This year will also mark the end of a four-year slide in console shipments.

The true impact of the PS4 and Xbox One, or Xbone, will be felt next year. Nintendo’s new Wii U hasn’t done very well this year, due to a lack of compelling games, but the competition is expected to do just fine.

The research also suggests Sony will take the lead, as its console is somewhat cheaper and users don’t seem too thrilled by some of Microsoft’s policies. IDC also expects game revenue derived through connected console channels to exceed PC prepaid revenue this year.

“The number of online console gamers around the globe is on pace to exceed 165 million by 2017,” said Lewis Ward, Research Manager, Gaming at IDC. “As a result, the opportunity to sell these gamers digital assets through Wii U, Xbox One, and PS4 online storefronts will grow substantially in the next several years.” Ward adds that the Chinese government’s recent decision to lift the ban on consoles should lead to millions of additional hardware bundle sales for the likes of Nintendo, Microsoft, and Sony within three years.

The introduction of new consoles just in time for the holiday season will obviously have a knock on effect on sales of console related accessories and peripherals, not to mention retail games.

However, it is worth noting that higher demand for consoles is not expected to have much of an impact on the PC gaming market. Recent research indicates that PC gaming is doing just fine and spending is growing by a CAGR of 3 percent. Console and PC gaming are no longer vying for the same consumer base and they are developing in parallel, without much in the way of cannibalisation.

Next-gen consoles will struggle

Posted on July 16, 2013 by - News

ps4The next generation of games consoles are expected to pass 133 million shipments in their first five years on the market, slightly down from 140 million for the previous generation.

ABI Research noted that, although the console refresh – with Microsoft’s Xbone and Sony’s PS4 – should inject some life into the market, niche consoles nibbling at their heels could shake it up and encourage more innovation than the big three would like.

New platforms, such as niche Android devices like Ouya and even Nvidia’s curiosity Project Shield, will promote different approaches to gaming. According to a report, new entrants will be able to raise existing platforms like Windows and Android as well as bridging the divide between fixed and mobile gaming.

We could even see low cost consoles emerging out of current generation technology in the $99 or less bracket.

According to senior ABI analyst Michael Inouye, without a shift in strategy Nintendo may suffer – as the casual gamers stick to mobile devices and Wii U pricing fails to bring about the success of the Wii.

Meanwhile, if China – which is mulling lifting a console ban – opens its borders to the big players, there could be a short term boost of current generation consoles, though this is not expected to alter next gen shipments too much.

Practice director Sam Rosen said ultimately, the future of console makers depends on balancing compelling content with competitive pricing.

“Without solid titles and first party franchises, platforms will have a difficult time finding traction, streaming media is not enough when low-cost smart set top boxes are readily available,” Rosen said. “While we don’t anticipate a drop-off in game console households, barring significant changes to less developed console markets in Asia and Latin America, there isn’t a great deal of growth opportunity beyond the current installed base”.

AMD to cut reliance on PC chips

Posted on April 24, 2013 by - News

AMD, SunnyvaleAMD might be on the verge of its biggest strategic shift in ages, as it starts to embrace ARM processors and more frugal chips. The company hopes to make as much as half of its money from console chips and ultra-low power processors by 2016. That is on top of ARM-based server chips which are already in the works.

At the moment, AMD generates the vast majority of its revenue from x86 processors and GPUs, but this year it is expected to ship millions of custom APUs for gaming consoles. On Tuesday the company launched a range of embedded x86 chips based on the new Jaguar core, but it also hinted at upcoming embedded chips based on ARM designs.

AMD already made it clear that it intends to use upcoming 64-bit ARM cores in its server parts, but the decision to design embedded APUs with ARM cores could have far reaching implications. In technical terms, these chips will have a lot more in common with consumer application processors than server chips. They are also expected to feature the latest generation Radeon graphics. In other words, AMD will develop ARM based SoCs, but it is still unclear whether it will target the consumer market.

Several years ago AMD sold its Imageon mobile graphics division to Qualcomm, and Qualcomm put it to good use, churning out millions of mobile SoCs with Adreno graphics, courtesy of AMD IP. However, AMD insists that it could catch up with relative ease.

Sasa Marinkovic, AMD’s Technology Marketing Lead, told Forbes that chip architecture at the time of the Imageon sale was full of bottlenecks and it has moved along since then.

“We sold some graphics IP, but we didn’t forget how to build it,” he said.

AMD already has some x86 designs capable of hitting sub-5W thermal envelopes required by tablet manufacturers, such as the 4.5W Temash SoC. However, ARM based chips could offer even better power efficiency and end up with sub-3W TDPs.

On the console front things are looking even better. AMD expects sales of custom APUs for the Playstation 4 and next-gen Xbox to account for 20 percent of its revenue by the end of the year. Similar chips based on the Jaguar core are coming to the consumer market as well.
