AMD's next-gen Trinity mobile APUs further detailed

Steve Dougherty | Oct 25, 2011 7:53 AM CDT

A bunch more details have surfaced today on AMD's upcoming "Virgo" PC platform which comprises their next-gen mobile "Trinity" APU using an FM2 package. The latest details confirm that Trinity will in fact be compatible with AMD's current-gen A75 "Hudson-D" chipset, but we are yet to learn whether or not FM1 and FM2 are pin compatible.

AMD's Trinity mobile APUs are 32nm based and run a TDP of up to 35W. The four x86-64 cores used are based on AMD's next-gen "Piledriver" architecture (rumoured to be between 10 and 15% quicker on average when compared to Bulldozer) and these four cores are arranged in two modules. Each of the two modules holds two cores and is given certain shared and dedicated resources.

The new APUs sport an integrated DDR3-2133MHz memory controller, up to 4MB (2MB per module) of L2 cache and Radeon HD 7000 series IGP (said to be about 30% quicker than Llano's iGPU). AMD is talking a 20% performance improvement over current-gen Llano APUs which comprise K10 "Stars" cores. A new 3rd generation form of TurboCore technology will also be included that gives superior power management and overclocking features.

Intel releases Core i7-2700K 3.5GHz unlocked LGA-1155 CPU

Steve Dougherty | Oct 24, 2011 8:31 AM CDT

As we learned about a month ago, Intel has been planning the release of a new processor model to rest atop the i7-2x00 line; that being the 2700K. And we we had also established at that time, the processor's release date is today.

The Core i7-2700K looks not to seperate itself much at all from the 2600K on paper with its quad-core, LGA1155 package on 32nm Sandy Bridge silicon, 256KB L2 cache per core and 8MB L3 shared cache. It clocks in at 3.5GHz, but does of course sport an unlocked base clock ratio multiplier, as denoted by the 'K'.

While we won't know for sure this early into its release, it's been rumoured that these 2700K chips are essentially cherry picked Sandy Bridge processors that could well give even higher overclocking ceilings on average when compared to the 2600K. But while it would be nice to say you'll get a guarenteed 5.0GHz on air when picking up one of these puppies, we'll have to wait a little bit first and see what the general consensus is from peoples overclocking experiences.

ARM unveil super efficient Cortex A7, set to be paired with A15

Anthony Garreffa | Oct 24, 2011 12:39 AM CDT

ARM has unveiled a new chip that is set to enable more efficient and affordable mobile processors. Cortex A7 is based on ARM's 28nm fabrication and reportedly consumes five times less power and measured just one-fifth the size of the 45nm Cortex A8, which is found inside Apple's A4, Samsung's Hummingbird and Texas Instruments' OMAP3.

ARM will compliment the efficiency by pairing the Cortex A7 with quicker, more power hungry processing cores. The A7 is set to pave the way for sub-$100 smartphones, which will boost adoption rates in developing regions. ARM CEO, Warren East told the BBC:

We can see the developed world moving on and mobile being the nexus for all sort of consumer electronics. In the Bric countries (Brazil, Russia, India and China) we are seeing catch-up. As we look forward these smartphones are going to be totally ubiquitous and in the much less developed areas...

AMD already working on a B3 revision of Bulldozer?

Steve Dougherty | Oct 18, 2011 12:36 PM CDT

Given the ill received launch of AMD's FX (Bulldozer) CPU family no thanks to the lack of what mattered most, performance, it's hard to imagine how AMD can do much to rise above anytime soon, or even maintain the foothold they had in the market previously in terms of offering a more aggressive price/performance alternative.

However, it's looking like AMD still may have another playing card up its sleeve yet; this in the form of a new (B3) revision of the chips being worked on. A mention of the new stepping was spotted in a public AMD document entitled "BIOS and Kernel's Developers Guide (BKDG) for AMD Family 15h Models 00h-0Fh Processors"

This is potentially a good sign if what we saw from the Phenom launch is anything to go by. Many of you would recall When the first B2 stepping processors in the Phenom lineup were found to be flawed by the TLB (translation lookaside buffer) issue, which incurred quite the performance hindrance of at least 10%. It wasn't until AMD rectified the issue with the launch of the B3 stepping Phenoms four months later that Phenom became a lot more attractive.

Fresh Ivy Bridge Roadmap indicates 77W Max TDP

Steve Dougherty | Oct 18, 2011 9:03 AM CDT

Thanks to a chunky roadmap leak via a Chinese forum earlier today, we can gather up some more spicey details on Intel's upcoming Ivy Bridge CPUs and associating platforms; also removing some of the haze thats still been surrounding it in terms of TDP ratings and backward/forward compatibility characteristics.

If said roadmaps are the real mcCoy, we can look forward to a maximum TDP of just 77W for the high-end models which is a good drop lower than the 95W peak for Sandy Bridge thanks to the brand new 22nm fab process. The diagram above seems like a bit of a dogs breakfast at first, but if you focus primarily on the upper region that's where the more interesting tid bits lie.

We can ascertain from this chart that just like Sandy Bridge, there will be unlocked 'K' series SKUs for Ivy Bridge as well; these of which top out at the aforementioned TDP of just 77W. Looking further down the chart, there are entries for quad core 65W 'S' and 45W 'T' SKUs not unlike Sandy Bridge, and also an SKU entry for a 35W dual core.

Samsung to produce quad-core A6 chips for future Apple iOS devices

Anthony Garreffa | Oct 18, 2011 2:28 AM CDT

Even amongst all the lawsuits, bitching and injunctions, Samsung are still producing the A6 quad-core mobile chip for future Apple iOS-based devices. It was previously reported that Apple had signed a deal with Taiwan Semiconductor Manufacturing Company (TSMC) last month to supply A6 chips, but that deal seems to be on shaky grounds now. The Korean Times is now reporting that Apple and Samsung have maintained their buyer and supplier relationship and will do so going forward for the foreseeable future.

The Korean Times cites an executive from an Apple parts supplier in Korea, where it says Apple have concluded that Samsung is a critical business partner and can't sever times with them just yet. Samsung is already producing the A6 processor for future iOS devices at a manufacturing plant based in Austin, Texas which opened back in 2007. TSMC will still manufacturer chips for Apple, but the volume is expected to be very low.

The reason behind this is that TSMC haven't stabilized their manufacturing process and Apple isn't willing to take the risk of switching suppliers under such circumstances. What of the legal issues between Apple and Samsung? The article does point out that during an interview with Samsung CEO Choi Gee-sung, in which he told reporters that Samsung is handling legal issues with Apple independently of their business relationship with Apple.

Intel shares i7 3960X (Sandy E) benchmark results

Steve Dougherty | Oct 15, 2011 5:12 AM CDT

While many will take these numbers with a grain of salt since they came direct from Intel, it's not hard to believe how strong performing Intel's Sandy E is up against its old aged X58/LGA1366 predecessor, and with the (quite disappointing) benchmarks out on Bulldozer, it only puts AMD in an even dimmer light.

Intel has shared some internal test results of its soon to be launched Core i7 3960X Extreme Edition processor; a six cored / 12 threaded beast clocked in at 3.3GHz with 15MB of cache. The results were directly compared to the top dog in Intel's current flagship platform, the Core i7 990X EE, which runs a stock clock of 3.46GHz.

A breakdown of all the results can be read via the source link below, but to summarize here, the i7 3960X looks to be about 15% quicker on average. Its best improvement was actually seen in 3DMark 11's Physics test where it bested the Core i7 990X by 36%. And throughout the tests there was one particular standout attribute; its memory benchmarks where it left the 990X for dead over and over and scored up to 111% better in some instances.

RumorTT: Intel to drop Core i7 2700K, wants to bulldoze the Bulldozer launch

Anthony Garreffa | Oct 10, 2011 5:14 AM CDT

Intel is currently staying quiet on whether there will be a new Core i7 introduced to combat the impending launch of AMD's Bulldozer, but it seems there is going to be a bigger, badder brother released in the LGA1155 lineup. It is rumored that Intel is going to drop the 2700K onto the market, which will be a minor clock speed increase over the already available Intel Core i7 2600K. The 2600K is a 3.4GHz part with the 2700K set to be a 3.5GHz part, with Turbo enabled those speeds will be 3.8 and 3.9GHz, respectively.

The 2600K known is for its super high overclocking ability, with 4.5GHz+ achievable with decent air cooling, so the 2700K should achieve the same type of overclock as its just a 2600K with an extra 100MHz in the trunk. The conservative speed bump will keep the gates open for a future 2800K, as Intel need to keep a space between regular Sandy Bridge and the Extreme chips. We should soon what happens, but there are already people who have cranked up an engineering sample of the 2700K to an impressive 5GHz on air cooling.

Impressive? It's impressive, with a silent K.

Samsung talks about the 32nm 1.5GHz Exynos SoC

Anthony Garreffa | Oct 2, 2011 11:00 AM CDT

Samsung's latest Exynos 4210 SoC is a great piece of tech, it powers their super smartphone, the Galaxy S II and is a very, very fast phone. The 4210 sports two ARM Cortex A9 cores running at 1.2GHz along with an ARM Mali-400 MP4 GPU. The A9 chip is equal to that of TI's outing, and a bit better than NVIDIA's Tegra 2. In various tests, the Mali-400 MP4 beats out all other smartphone GPUs that have been tested.

Samsung have today announced a 32nm addition to the family, the Exynos 4212. CPU clock speeds get a nice bump up to 1.5GHz, but GPU clocks are unknown. Samsung is however claiming that GPU performance improves by up to 50% "over the previous processor generation". The move to 32nm could have allowed a 50% increase in clock speed. Samsung's 32nm process uses high-K + metal gate transistors, similar to Intel's transition to 45nm.

According to Samsung, these new transistors allow for either a 40% (or more) increase in performance at the same leakage or a 10x reduction in leakage current at the same speed. Density also improves by 2x enabling even more complex chip designs (more cores, bigger GPUs, more integration) or smaller die with the same feature set (which will eventually improve supply and profit). The Exynos 4212, Samsung is claiming a 30% reduction in power compared to its predecessor.

AMD FX-8150 to take on Core i7-980X and 2600K, pushes them up against a wall and mugs them of their price-performance crown

Anthony Garreffa | Sep 26, 2011 1:00 AM CDT

AMD's Bulldozer is set to enter the construction site shortly, and these new benchmarks are leaned heavily in their favor. It looks as though a set of leaked press slides of the AMD FX Processor found their way into the grubby hands of DonanimHaber ahead of the official launch with AMD claiming huge performance leads over rival, Intel. AMD claims that their FX-8150 processor is aiming to take down Intel's Core i7-980X in game tests and even passing it in some DirectX 11 titles.

It's performing on the same level as the Core i7 2600K in several popular CPU benchmarks such as WinRAR 4, X.264 pass 2, Handbrake, 7Zip, POV Ray 3.7, ABBYY OCR, wPrime 32M, and Bibble 5.0. The AMD FX-8150 benefits greatly from the FMA4 instruction set that is lacking in Intel's Sandy Bridge. In the OCL Performance Mandelbrot test, the FX-8150 thrashes the 2600K by as much as 70%.

But, performance isn't everything to a lot of people. Considering that the FX-8150 is confirmed to hover at around $250, we should see massive love for AMD's new Bulldozer processor.
