AMD details new mobile, server roadmaps

At the end of the Fusion Developer Summit, Mark Papermaster, AMD Executive VP and CTO, produced some roadmaps which provided us a small glimpse into the future plans of AMD. AMD is looking to bring three new APUs to market in 2013 and 3 new server chips later this year. With the come new updated core architectures.

Let's start with the APUs. AMD is planning 3 different versions for various markets. The top APU is codenamed 'Kaveri' and will feature 4 Steamroller cores. Steamroller is the successor to the Bulldozer/Piledriver cores. This APU will feature fully shared memory with the GPU and have 15-35W thermal envelopes and be used in 13.3-15.6" notebooks with thicknesses of 0.83" or less.

 

The middle APU is codenamed 'Kabini' and will be the successor to the Zacate and Ontario APUs. The Kabini APU will sport Jaguar cores which are the next iteration of the Bobcat core architecture. Thermals will be in the 9-25W range and be used in 11.6-15.6" notebooks with thicknesses in the neighborhood of 0.71-0.94". The bottom APU, 'Temash,' will be similar and manage to fit into a thermal envelope of 3.6W. Wow.

RumorTT: Sandy Bridge to have last hurrah in Q3, Ivy Bridge to take over

DigiTimes is reporting that Intel are to begin the phasing out of their Sandy Bridge-based processors this September. This paves the way for Ivy Bridge to get slapped into various products such as the Ultrabooks Intel are pushing big time.

 

TweakTown image news/2/4/24566_08_rumortt_sandy_bridge_to_have_last_hurrah_in_q3_ivy_bridge_to_take_over.jpg

 

Intel have said that OEMs have already begun receiving shipments of Ivy Bridge CPUs, with customers starting to notice them in systems later this month. Intel have also hinted that they expect to ship some 50-percent more Ivy Bridge CPUs in six months that it did in the same time period with Sandy Bridge.

 

But, there is a but here, folks. Ivy Bridge-based CPUs are much more expensive than their Sandy Bridge counterparts. According to DigiTimes, the price disparity is around $67-$100 per unit. This is a big problem for OEMs who are working on razor-thin margins on mainstream products that are the norm. If the Sandy Bridge chips do start disappearing in September, we should expect price cuts sometime this summer.


Desktop Trinity APU details revealed

AMD has announced some more details on its upcoming Trinity APUs destined for desktops. AMD has stated that these chips will start to appear in all-in-one PCs by the end of the month. Curiously, this is contrary to what several motherboard manufacturers told TechReport while at Computex. They had said that desktop parts were delayed.

 

TweakTown image news/2/4/24560_1_desktop_trinity_apu_details_revealed.png

 

It looks as though AMD may be respinning the silicon for the retail desktop chips, so it probably won't be identical to the chips OEMs will be receiving this month. That aside, we do know the models which will be becoming available this month. The chips are almost identical to the mobile chips, except that they will be clocked higher.

 

All of the CPUs feature a quad-core CPU based upon the new Piledriver architecture and 4MB of L2 cache. They will support up to DDR3 at 1866MHz and slip into the FM2 socket. The K series denotes chips that are unlocked for overclockers, so if you plan to overclock, make sure to pay attention and get the correct model.

G.Skill booth featured some of the world's best overclockers on stage

Computex 2012 - Overclocking is a huge thing here in Computex, where at the G.Skill booth they had some of the world's best overclocking champions facing it off on-stage. Young Pro, Hiwa, and Fred Yama were all there as we walked past.

Intel releases info on 14 new dual-core Ivy Bridge-based CPUs ahead of Computex

Ahead of Computex next week, Intel have released details on 14 new dual-core Ivy Bridge-based processors. Core i5 and i7 processors will be among the first to drop, with Core i3 variants arriving later this year.

 

TweakTown image news/2/4/24397_22_intel_releases_info_on_14_new_dual_core_ivy_bridge_based_cpus_ahead_of_computex.jpg

 

The Core i3 processors will also be joined with new Pentiums and Celerons, too. Out of the 14 new dual-core processors, six of them are desktop-grade, which means the remaining 8 of them are destined to mobile and ultra-low voltage. Ultra-low voltage chips sport a "U" in their name, which gives their identity away.

 

With Computex happening next week, we should expect to see a slew of Ultrabooks sporting the new ultra-low voltage Core processors. We should have a bunch of hands-on talk with various models, chips, Ultrabooks and so forth, so check back each and everyday next week for our coverage of Computex!

RumorTT: AMD FX 8150 appears to have hit 8805.6MHz in new overclock

The AMD FX series of processors is known for overclocking pretty well. It currently holds the world record for fastest clock speed ever achieved and looks to be breaking that once again. A new CPU-z validation screen shot has shown up online. It details the feat even though HWBot rejected the the posting.

 

TweakTown image news/2/4/24338_1_rumortt_amd_fx_8150_appears_to_have_hit_8805_6mhz_in_new_overclock.jpg

 

The rejection was most likely due to the fact that the overclocker didn't provide much in the way of detail about the cooling system used. When I say much, I mean any. What we do know is that the chip was clocked at a massive 8805.6MHz and was achieved by overclocker Ksin. Speed like that comes only when an overclocker uses extreme cooling such as liquid nitrogen or liquid helium.

 

To achieve the feat, Ksin used a base clock of 303.29 MHz and a multiplier of 29.0. To reach these clock speeds, an incredible 1.86 volts were pumped through the core. As such, it is recommended that you don't try this at home as that will kill your chip very quickly. Other components of the system include an ASUS Crosshair V Formula motherboard and 4 GB (2x 2 GB) of ADATA memory. The memory was clocked at 1417 MHz.

 

It appears that the posting has now been removed at the time of writing. I imagine this is due to the lack of cooling information.

 

UPDATE: The reason that the score was pulled from HWBot is because the Pi score indicated that the frequency could be bugged. This doesn't mean that it is, but that the possibility exists.

RumorTT: AMD Piledriver FX CPU production to begin Q3 2012

"Industry sources" are reporting that the next-generation AMD architecture code-named "Piledriver" will commence production in Q3 2012. Bulldozer, Piledriver's predecessor, was only released in October of 2011, so this could match Intel's one year release cycle. Trinity, an APU based upon Piledriver was released just last week.

 

TweakTown image news/2/4/24296_1_rumortt_amd_piledriver_fx_cpu_production_to_begin_q3_2012.jpg

 

The upcoming CPU will continue to be based upon the AM3+ platform. This simple fact should keep enthusiasts happy and will allow for current Bulldozer users to upgrade for only the cost of a CPU. AMD has always had a history of retaining sockets and providing upgrade paths whereas Intel often kills off sockets with each new processor.

 

Piledriver will be very similar to Bulldozer in that it will be made on a 32nm process and feature the same compute module design. Piledriver will also retain the same dual-channel 1866MHz DDR3 memory controllers. Piledriver will continue to feature AMD's Turbo Core at version 3.0. The new CPU will deliver more performance, thanks to an improved IPC, at lower power usage, thanks to AMD's new energy-recycling technology called resonant clock mesh.

AMD continue to fib on their transistor count, this time with the Llano Fusion APU

If we remember late last year, AMD had talked about the transistor count in their then-released Bulldozer chip, which was meant to house 2 billion transistors, but actually only had 1.2 billion. How a mistake like that can happen is anyone's guess, but it looks like Team Red are up to their old tricks again, it seems.

 

TweakTown image news/2/4/24277_07_amd_continue_to_fib_on_their_transistor_count_this_time_with_the_llano_fusion_apu.jpg

 

Bright Side of News has an interesting piece, where they've noticed that AMD have again given the public an erroneous transistor count. AMD's Llano was meant to have 1.45billion transistors, as the company explained at the Hot Chips 2011 conference, as well as most reviews citing that it sported 1.45 billion transistors.

 

But, if we look at some of the Trinity reviews, such as AnandTech's, where they state it has 1.178 billion transistors, Tom's Hardware and Tech Report state it has 1.45 billion, but Trinity actually sports 1.30 billion transistors. The die size hasn't changed, and measures in at the same 228mm² since Llano emerged in 2011. Most sites can't really be faulted here, as they've just copy/pasted the specs directly from... AMD.

 

AMD are just filling their bra with tissues, and flashing their Llano boobies everywhere. But when that bra comes off, you're left looking at a ground covered in tissues. We still love you, AMD, but what's going on?

Computing researchers show super efficient 'Inexact' microprocessor

Researchers from Rice University in Houston, Singapore's Nanyang Technological University (NTU), Switzerland's Center for Electronics and Microtechnology (CSEM) and the University of California, Berkeley have unveiled an "inexact" chip at the ACM International Conference on Computing Frontiers in Cagliari, Italy.

 

TweakTown image news/2/4/24183_1_computing_researchers_show_super_efficient_inexact_microprocessor.jpg

 

The chip is allowed to make mistakes in order to gain speed and energy usage advances. This new "inexact" processor is up to 15 times more efficient than current processors. It can be used in certain applications where 100% accuracy isn't mission critical. Examples of this would be video or picture processing.

 

"It is exciting to see this technology in a working chip that we can measure and validate for the first time," said project leader Krishna Palem, who also serves as director of the Rice-NTU Institute for Sustainable and Applied Infodynamics (ISAID). "Our work since 2003 showed that significant gains were possible, and I am delighted that these working chips have met and even exceeded our expectations."
