AMD’s Trinity processor vs. Intel’s Ivy Bridge

May 22nd, 2012

AMD’s next-generation A-Series processors, code-named Trinity, are the chip manufacturer’s answer to Intel’s new Ivy Bridge processors now appearing in the new Ultrabook laptops.

How much of an improvement do the new Trinity chips offer laptop users and can these new Trinity-based laptops compete against Ivy Bridge? The reviews are in.

Every new generation of chips promises better performance and energy efficiency, and Trinity is no exception. Earlier this year, AMD claimed Trinity would offer significant improvements over its current Llano chips: An overall performance increase of up to 25%, 50% better graphics performance, and double the performance per watt.

Across the web, tech reviewers have been benchmarking an AMD Trinity test laptop (featuring the A10-4600 quad core processor with integrated Radeon HD 7760G graphics) to put these claims to the test. We’ll have our own tests from the PCWorld Labs soon, but this is how the new accelerated processing unit (APU) is being received so far:

Modest General Performance Improvements: Not Enough to Best Intel

Intel is still the market leader in this highly competitive chips race and, unfortunately, going on CPU performance alone, Trinity still lags behind. Both VR-Zone and HotHardware say the Trinity A10 gets “blown out of the water” by Intel’s Ivy Bridge Core i7 CPU–and even against Intel’s second-generation Sandy Bridge mobile chips in some tests.

AMD positions its top-of-the-line A10 series against Intel’s lower-end Core i7 and higher-end Core i5 chips. Yet an Ivy Bridge mid-range i5-2410M had a 25% CPU performance advantage over the Trinity A10-4600, according to AnandTech’s comparisons using PCMark.

VR Zone is frank in its assessment, calling Trinity’s single threaded applications and raw memory performance “abysmal.”

Still, AnandTech says Trinity’s new is a step forward from the CPU cores used in Llano. Trinity was about 20% faster than Llano in the reviewer’s general CPU performance tests–close to AMD’s 25% promise.

(Intel’s Ivy Bridge CPU gains over its Sandy Bridge processor were also modest: About 5 to 10% faster in PCWorld tests.)

Great Integrated Graphics, Gaming Performance

As with Intel’s Ivy Bridge, AMD Trinity’s biggest gains are on the graphics side. Tom’s Hardware found Trinity “soundly beating its competition” in graphics processing and–as you see in this chart–in this testing, Trinity leads even against a Llano laptop with a discrete graphics card (the older 3DMark Vantage metric was used to compare against the Intel Sandy Bridge chip, which doesn’t support DirectX 11).

Trinity even bests Intel Ivy Bridge’s impressive graphics performance: The HD7760G integrated graphics processor (IGP) had a 30-percent to 50+-percent performance gain over the Intel HD 4000 IGP in an Ivy Bridge Core i7 chip, according to HotHardware.

This finding would make Trinity really impressive for gaming. Hexus said the chip “offers best-in-class performance and enough grunt to play modern games at reasonable image-quality settings.” In AnandTech’s tests, Trinity had an average 20% lead against Ivy Bridge when comparing performance over 15 game titles. For 11 out of the 15 games, Trinity came out on top.

Significantly Better Battery Life AMD also managed to significantly improve battery life on Trinity compared to previous AMD chips and even when compared to Ivy Bridge–even though Intel uses a new 22nm production technology, while Trinity still uses the 32nm process of older Llano chips (smaller chips tend to be more energy efficient).

In this AnandTech chart, look at the red bar for Trinity, orange for Llano, and dark green for the Asus laptop equipped with an Ivy Bridge processor to see the battery life performance differences.

AMD claims 50% better battery performance from a Trinity laptop versus Llano–up to 8.5 hours of browsing or 4 hours of YouTube video streaming, according to Slashgear.

Conclusion

Taking the synthetic test results (on a prototype laptop) with a grain of salt, an AMD Trinity-based laptop may tempt you, depending on your needs.

If you require a mobile powerhouse with the best processing performance possible, an Intel quad-core i7 will be your better bet. But if you’re a gamer or want longer battery life in your laptop, AMD has an edge over Intel.

And despite the less-than-overwhelming overall CPU performance gains, Trinity-based laptops will be more than fine for mainstream tasks.

Also not to be dismissed: Trinity-equipped laptops will, in general, be cheaper than laptops equipped with Ivy Bridge processors. For instance, AMD’s ultrathin laptops are set to be priced about $200 lower than Intel Ultrabooks.

The HP Envy Sleekbook with AMD processor is the first example of this; the Sleekbook is $150 cheaper than HP’s new Envy Ultrabooks with Intel processors.

Stay tuned for more AMD Trinity-based laptop news and reviews.

Intel Touts 3rd-Gen Core vPro CPUs, Security And IT Focused

May 16th, 2012

Intel’s 3rd-generation Core i7 CPUs are certainly forces to be reckoned with, but they aren’t the best option for most businesses. In order to give enterprise users an option, too, the company’s introducing a 3rd wave of their Core vPro CPUs. These units are shipping now, aimed at notebooks (Ultrabooks included) across the IT landscape.

To defend against identity theft, Intel introduced Intel Identity Protection Technology with public key infrastructure into Intel Core vPro processors. The technology provides a new second layer of authentication embedded into the PC that allows websites and business networks to validate that a legitimate user is logging in from a trusted PC by using a private key stored in a PC’s firmware. Intel has been working with solution providers and online Web properties such as Feitian, InfoSERVER, Symantec and VASCO to take advantage of Intel IPT technology to ultimately safeguard users’ identity. Clearly, enterprise features are at the heart of these chips.

The Intel Core vPro Processor family includes Intel Active Management Technology (Intel AMT) to remotely manage computing issues. For example, retailers with point-of-sale machines, digital signs or other intelligent devices can remotely diagnose and fix problems over the network. Further details can be found in the Via link below; no word on when actual machines with the new vPro gear will start to ship, though.

AMD Trinity A10-4600M Processor Review

May 15th, 2012

AMD’s second-generation Bulldozer core processor microarchitecture, codenamed Piledriver, has made headlines at HotHardware many times in the past few months, including our CES sneak peek of the chip that AMD is launching today for the mobile market, codenamed Trinity. What this launch is all about is AMD’s answer to Intel’s Ivy Bridge-based Core series processors for notebooks. It’s that straightforward, though we’ll start by level-setting expectations based on how both companies and their respective architectures approach computing workloads.

For AMD, Trinity has also been reported as offering much-needed performance enhancements in IPC (Instructions Per Cycle) but also more of the same strength in gaming and multimedia horsepower, with an enhanced second generation Radeon HD graphics engine.

In the pages ahead, we’ll dive into AMD’s new Trinity architecture and AMD’s new A10 series APU, along with lots of benchmark data looking at the results of AMD’s recent efforts from a number of angles.

Linux running on an 8-bit processor

April 2nd, 2012

Being told that Linux requires a 32-bit processor, 1MB of memory, and a MMU (Memory Management Unit) as an absolute minimum wasn’t good enough for Dmitry Grinberg. When he saw threads on microcontroller boards asking whether Linux could run on an 8-bit microprocessor, the responses were full of ridicule, and outright dismissed the possibility.

In an attempt to prove the naysayers wrong, Dmitry went on to create an 8-bit computer using an ATmega1284p processor, a 16MB 30-pin SIMM, and a 1GB SD card for storage, all connected on a prototyping breadboard.

To emulate a 32-bit processor and the MMU, Dmitry had to write an ARM emulator. He decided against porting existing emulator due to the way AVR compiles to machine code, stating the issue of bit shifting integers by 20 causing zero values, among other potential problems. Working around these pitfalls would require careful modification of exiting code, a tedious and error-prone excersise.

A serial connection between the 8-bit computer and a modern 32-bit PC allows Dmitry to type commands and see the mini PC in action. The PC does not require this connection to function, and it can be modified to use its own LCD and keyboard.

For reference, the processor at the heart of this design runs at a grand total of 20MHz, has a two stage pipeline, and costs around $6. Also interesting to note is that Dmitry overclocked the processor to 24MHz. Factoring in the large overhead of the emulator, it was estimated that the effective clock rate is 6.5KHz (yep, kilohertz!)

Surprisingly the completed project actually works! Granted, it’s a little slow, but it can boot Ubuntu, which proves that you can actually run Linux on less than minimum spec. To quote Dmitry, “It takes about 2 hours to boot to bash prompt (“init=/bin/bash” kernel command line). Then 4 more hours to boot up the entire Ubuntu (“exec init” and then login). Starting X takes a lot longer.”

What’s really neat about the project is that it’s possible to build your own. The pin-outs, hardware spec and source code are all provided on Dmitry’s webpage. If you’re not willing to do it yourself, you can see it in the video below (it’s in 3x speed).

XMOS adds analog to processor for audio apps

March 22nd, 2012

The XS1-S adds a 180-nm analog interface and power management IC to the 65-nm digital chip inside the original XS1 to improve performance and help the family address audio applications.

The XS1-S family delivers up to 700 MIPS of real-time performance per core with integrated analog functionality which allows low latency digital audio interfaces. The first two products available in the XS1-S Family are the single core device: XS1-SU1 and the dual core device: XS1-SU2.

The analog functionality includes an integrated USB 2.0 High Speed Phy, making the XS1-S chips suitable for USB audio interfaces, DJ products, USB speakers, and intelligent USB peripherals.

The analog chip also includes an independent oscillator circuit. “As the market turns increasingly to computer-based recording equipment makers are looking for lots of channels, high quality, low latency, and flexibility,” said co-founder Ali Dixon who serves as marketing manager.

It is also good for bridging functions such as USB to JTAG. Although XMOS appears to have found a rather narrow niche for itself in audio applications, Mark Lippett, vice president of engineering, said it is about focus. “We are doing some work in other verticals,” he said. Nonetheless, audio apps provide plenty of opportunities and peripheral designs could allow tablet computers to become essential DJ hardware that can be interfaced to music systems. Without mentioning a certain computer company Lippett observed that iOS5.0 now supports multichannel audio.

Software support is now provided for a number of digital protocols including I2S, TDM, SPDIF AES/EBU and the analog support IC includes a 12-bit 1-megasample per second ADC, and the chip wraps a lot of the peripheral circuitry that customers were previously adding to the digital-only XS1 chips.

“Our customers have shipped more than half a million USB audio products using XS1 devices. The higher performance, integrated XS1-S Family and its accompanying software and tools deliver the ideal solution to an even broader range of audio applications,” said Tom Lee, XMOS vice president of sales and marketing, in a statement.

XMOS processors combine flexible interfacing, control, and data processing in a single device. The devices, including all digital peripherals, are programmed in software using a C-language development flow, providing both application and I/O flexibility even after deployment.

The XMOS customer list includes: Audio Partnership, High Resolution Technologies, Native Instruments, Vestax, Bluemic, Propellerhead; all well-known names in either highest fidelity consumer or in professional and semi-professional music equipment. And since the company’s formation in 2005 the company has dealt with more than 1,000 customers and has more than 100 customers who are shipping in volume.

Intel Rolls Out New ‘Berryville’ Atom CE5300 Media Processor

March 21st, 2012

Intel unveiled its new Atom CE5300 media processor at the IPTV World Forum in London this week. Codenamed “Berryville,” the Atom CE5300 part is a System on Chip (SoC) designed to power the next generation of set-top boxes and media gateways, Intel says. Details are fairly light at this point, though we do know it’s a 32nm dual-core chip with support for hyperthreading and virtualization. According to Intel, it also has an advanced 3D/2D graphics engine, integrated power management, and an H.264-B picture hardware encoder baked in.

The hype machine is working full throttle on this one.

“This new chip from Intel will enable you to video conference with friends and family from your big screen TV in the living room. You’ll be able to show your girlfriends your new dance moves without having to worry about getting your laptop camera aimed properly,” Intel said. “Also imagine a great new 3D user interface and console-level graphics for gaming with this high performance chip in set-top boxes.”

Sounds great, doesn’t it? To clarify, we’re talking about “console-level graphics” and not Intel’s assumption that you have “girlfriends” (plural).

The Atom CE5300 represents Intel’s fourth generation SoC and its first dual-core CE part. No word one when Intel expects it to start shipping.
