Tagged: ultrabook, Intel, haswell, cpu, 10w tdp
Intel’s next generation Haswell CPU architecture is set to lower the bar even further on power efficiency by requiring only 10W of cooling. As the company’s mainstream processor, and replacement for Ivy Bridge, it is set to launch in the first half of 2013.
Haswell will be based on a new socket called LGA 1150, and is said to feature incremental performance improvements over Ivy Bridge. Further, Haswell CPUs will include one of three tiers of GT1, GT2, or GT3 processor graphics along with the AVX2 instruction set.
What is interesting about the recent report by The Verge is that previous rumors suggested that Haswell would have higher TDP ratings than both Sandy Bridge and Ivy Bridge. Considering Ivy Bridge has several 35W desktop models, and a few 17W mobile parts, the reported 10W TDP of Haswell seems to indicate that at least the mobile editions of Haswell will actually have much lower TDPs than Ivy Bridge. (It is not clear if detkop and non ultra-low-voltage (ULV) chips will see similar TDP improvements or not.)
The 10W TDP would mean that ultrabooks and other thin-and-light laptops could use smaller heatsinks and suggests that the processors will be more power efficient resulting in battery life improvements (which are always welcome). The Verge further quoted an Intel representative in stating that "It's really the first product we're building from the ground up for ultrabook."
While the lowest-power Haswell chips won’t be powerhouses on the performance front, with the improvements over Ivy Bridge to the CPU and GPU it should still handily best the company’s Atom lineup. Such a feat would allow Haswell to secure a spot powering future Windows 8 slates and other mobile devices where Atom is currently being used.
Just the fact that Intel has managed to get its next generation mainstream CPU architecture down to 10W is impressive, and I’m looking forward to see what kinds of devices such a low power x86-64 chip will enable.
Stay tuned for more Haswell news as the Intel Developer Forum (IDF) next week should be packed with new information. Here's hoping that the desktop chips manage some (smaller) TDP improvements as well!

Tagged: sandy bridge, Ivy Bridge, Intel, core i3, 35w
Back in March of this year, Intel launched a slew of third generation Core Ivy Bridge processors. At the high end sat the Core i7-3770K with 4 cores, hyperthreading, 3.5 GHz clockspeed (3.9 GHz Turbo Boost), 8 MB L3 cache, and a 77W TDP for $332. The lineup went down in features – and price – from there all the way to the Core i5-3330S. The 3330S had four cores, 6 MB of L3 cache, a 65W TDP, and a clockspeed of 2.7 GHz (3.2 GHz Turbo Boost). Further, just about every CPU that was not a K, S, or T edition came equipped with the older HD 2500 integrated processor graphics. While the list comprised 18 new processors, the lower-end Core i3 Ivy Bridge CPUs were noticeably absent.
Fortunately, FanlessTech has managed to get ahold of pricing and specifications for five of those lower cost Intel chips. The new additions to Intel's lineup include three Ivy Bridge processors and two Sandy Bridge CPUs. Specifically, we have the i3-3240T, i3-3220T, Pentium G2100T, Pentium G645T, and Pentium G550T. All of those parts have a TDP of 35W and are priced very affordably.
|Model||Cores / Threads||Clockspeed||L3 Cache||TDP||Launch Price ($USD)|
|i3-3240T||Ivy Bridge||2/4||2.90 GHz||3MB||35W||$138|
|i3-3220T||Ivy Bridge||2/4||2.80 GHz||3MB||35W||$117|
|Pentium G2100T||Ivy Bridge||2/2||2.60 GHz||3MB||35W||$75|
|Pentium G645T||Sandy Bridge||2/2||2.50 GHz||3MB||35W||$64|
|Pentium G550T||Sandy Bridge||2/2||2.20 GHz||2MB||35W||$42|
The Core i3-3240T and i3-3220T are dual core Ivy Bridge processors build on a 22nm process, and are priced at just over $100. The cheapest Ivy Bridge CPU is actually the Pentium G2100T at $75 so the barrier to entry for Intel’s latest chips is much lower than it was a few months ago. Intel’s second generation Core architecture is still alive and kicking as well with the Pentium G645T and G550T at $64 and $42 respectively.
Two specifications are still unkown: Turbo Boost clockspeeds (if any) and which version of processor graphics these chips will feature. On the graphics front, I think HD 2500 is a safe bet but Intel may throw everyone a curve ball and pack the higher-end processor graphics into the low end units – which are arguably the (computers) that need the better GPU the most.
Granted, these lower cost processors are not going to give you near the performance of the i7-3770K that we recently reviewed, but they are still important for low power and budget desktops. Bringing the power efficiency improvements of Ivy Bridge down to under $100 is definitely a good thing.
As far as availability, you can find some of the new low TDP processors at online retailers now (such as the Core i3-3220T), but others are not for sale yet. While I do not have any exact dates, they should be available shortly.
How would you put these low TDP dual cores to work?
Ah, the end of August. School is about to start. American college football is about to get underway. Hot Chips is now in full swing. I guess the end of August caters to all sorts of people. For the people who are most interested in Hot Chips, the amount of information on next generation CPU architectures is something to really look forward to. AMD is taking this opportunity to give us a few tantalizing bits of information about their next generation Steamroller core which will be introduced with the codenamed “Kaveri” APU due out in 2013.
AMD is seemingly on the brink of releasing the latest architectural update with Vishera. This is a Piledriver+ based CPU that will find its way into AM3+ sockets. On the server side it is expected that the Abu Dhabi processors will also be released in a late September timeframe. Trinity was the first example of a Piledriver based product, and it showed markedly improved thermals as compared to previous Bulldozer based products, and featured a nice little bump in IPC in both single and multi-threaded applications. Vishera and Abu Dhabi look to be Piledriver+, which essentially means that there are a few more tweaks in the design that *should* allow it to go faster per clock than Trinity. There have been a few performance leaks so far, but nothing that has been concrete (or has shown final production-ready silicon).
Until that time when Vishera and its ilk are released, AMD is teasing us with some Steamroller information. This presentation is featured at Hotchips today (August 28). It is a very general overview of improvements, but very few details about how AMD is achieving increased performance with this next gen architecture are given. So with that, I will dive into what information we have.

Tagged: amd, am3+, fx-4130
AMD has good news for those looking to build or upgrade an AMD powered system as they are lowering their prices on processors across the board as well as adding the new four core Socket AM3+ FX-4130, with a 3.8GHz base clock and 3.9GHz in Turbo. It is not yet for sale but is expected to retail for $112, easily affordable for most users looking for a lower cost system.
"The value proposition for the first generation AMD A-Series APUs is also compelling: A quad-core CPU and a DirectX® 11 highly-capable gaming GPU on a single-chip with more than 500 GFLOPs of compute power, for under $100 (A8 3850). Working together, the CPU and GPU can accelerate a range of applications to outperform a stand-alone CPU in some use cases. The lower-power first generation AMD A-Series APUs are even more affordable and are receiving positive reviews for small-form factor HTPCs as well. Price reductions across the first generation AMD A-Series APUs stack are in effect now, so please check your local retailer!"

Tagged: linux, Ivy Bridge, Intel, i5-3470, hd 2500
The new Ivy Bridge processors introduced a new member of Intel's graphics processor called the HD 2500, which has received less than positive reviews as the previous HD 3000 outperforms it. However those tests were for Windows applications and games, whereas the testing at Phoronix specifically pertains to the performance under Linux. They compare the i5-2400S, i5-2500K, i5-3470, and i7-3770K together in a series of benchmarks to not only test the performance but also their compatibility with Linux. It seems that perhaps the performance of the HD3000 and HD2500 are much closer in Linux than they were running under Windows, though both still lose out to the HD4000.
"Since the launch of Intel's Ivy Bridge processors earlier this year there have been many benchmarks of the Intel Core i7 3770K with its integrated HD 4000 graphics and then more recently have been Linux testing of the Intel Core i7 3517UE from the CompuLab Intense-PC and Intel Core i7-3615QM as found on the Apple Retina MacBook Pro. The newest Intel Ivy Bridge chip to play with at Phoronix is the Intel Core i5 3470, which bears an Intel HD 2500 graphics core. In this article are benchmarks of the Intel HD 2500 Ivy Bridge graphics with the open-source Intel Linux graphics driver stack."

Tagged: Z77, motherboard, mini-itx, Intel, gigabyte, ga-h77n-wifi
During a European roadshow, Gigabyte showed off a new Mini-ITX form factor motherboard for the first time. Called the GA-H77N-WIFI, the motherboard is well suited for home theater and home server tasks. Based on the H77 chipset, it is compatible with the latest Intel Core i3 (coming soon), i5, and i7 "Ivy Bridge" processors. The board goes for an all-black PCB with minimal heatsinks on the VRMs, and the form factor is the same size as the motherboard that Ryan recently used in his Mini-ITX HTPC build.
The GA-H77N-WIFI features a LGA 1155 processor socket, two DDR3 DIMM slots, PCI Express slot, two SATA 3Gbps ports, two SATA 6Gbps ports, and an internal USB 3.0 header. There are also two Realtek Ethernet controller chips and a Realtek audio chip.
- 1 PS/2 port
- 2 USB 3.0 ports
- 2 HDMI ports
- 1 DVI port
- 2 Antenna connectors (WIFI)
- 4 USB 2.0 ports
- 2 Gigabit Ethernet ports
- 1 Optical S/PDIF port
- 5 Analog audio jacks
The dual Gigabit Ethernet ports are interesting. It could easily be loaded with open source routing software and turned into router/firewall/Wi-Fi access point. To really take advantage of the Ivy Bridge support, you could put together a nice media server and HTPC recording/streaming box (using something like SiliconDust's HDHomeRun networked tuners or Ceton's USB tuner since this board is very scarce in the way of PCI-E slots). What would you do with this Mini-ITX Gigabyte board?
Unfortunately, there is no word yet on pricing or availability, but the motherboard is likely coming soon. You can find more information on the motherboard over at tonymacx86, who managed to snag get some photos of the board.

Tagged: Ivy Bridge-E, Intel
According to VR-Zone, an Intel roadmap has surfaced which outlines the upper end of the company’s CPU product line through the end of 3rd Quarter 2013. The most interesting albeit also most confusing entry is the launch of Ivy Bridge-E processors in the quarter after the Haswell mainstream parts.
So apparently the lack of high-performance CPU competition unhooked Intel’s tick-tock-clock.
The latest Intel CPU product roadmap outlines the company’s expected product schedule through to the end of Q3 2013. The roadmap from last quarter revealed that Intel’s next architecture, Haswell, would be released in the second quarter of 2013 with only Sandy Bridge-E SKUs to satisfy the enthusiasts who want the fastest processors and the most available RAM slots. It was unclear what would eventually replace SBE as the enthusiast part and what Intel expects for their future release cycles.
I can Haswell-E’zburger?

Latest rumors continue to assert that Sandy Bridge-E X79 chipset-based motherboards will be able to support Ivy Bridge-E with a BIOS update.
The downside: personally, not a big fan of upgrading CPUs frequently.
In the past I have never kept a motherboard and replaced a CPU. While I have gone through the annoyance of applying thermal paste – and guessing where Arctic Cooling stains will appear over the next 2 weeks – I tend to even just use the default thermal tape which comes with the stock coolers. I am not just cheap or lazy either; I simply tend to not feel a jump in performance unless I allow three to five years between CPU product cycles to pass by.
But that obviously does not reflect all enthusiasts.
But how far behind on the enthusiast architectures will Intel allow themselves to get? Certainly someone with my taste in CPU upgrades should not wait 8-10 years to upgrade our processors if this doubling of time-between-releases continues?
What do you think is the future of Intel’s release cycle? Is this a one-time blip trying to make Ivy Bridge scale up or do you expect that Intel will start releasing progressively more infrequently on the upper end?

Tagged: x86-64, x86, MIPS, Jim Keller, arm, amd, Alpha
There has been quite a bit of news lately from AMD, and very little of it good. What has perhaps dominated the headlines throughout this past year was the amount of veteran AMD employees who have decided (or were pushed) to seek employment elsewhere. Not much has been said from these departing employees, but Rory Read certainly started things off with a bang by laying off some 10% of the company just months into his tenure.
Now we finally have some good news in terms of employment. AMD has hired a pretty big name in the industry. Not just a big name, but a person who was one of the primary leads on two of AMD’s most successful architectures to date. Jim Keller is coming back to AMD, and at a time where it seems AMD needs some veteran leadership who is very in touch with not just the industry, but CPU architecture design.
Jim was a veteran of DEC and worked on some of the fastest Alpha processors of the time. Much could be written about DEC and how they let what could have been one of the most important and profitable architectures in computing history sit essentially on the back burner while they focused on seemingly dinosaur age computing. After the Alpha was sold off and DEC sold away, Jim found his way to AMD and played a very important role at that company.
The first product was helping to launch the K7, and worked primarily with system engineering. The vast majority of design work for the K7 was finished by the time he signed on, but he apparently worked quite a bit on integrating it into the new socket architecture that was derived from the DEC Alpha. Where Jim really earned his keep was in co-authoring the x86-64 specification and being lead architect on the AMD K8 series of processors. While he left in 1999, the mark he left on AMD is essentially indelible.
After AMD he joined Sibyte (Broadcom) and was lead architect on a series of MIPS processors used in networking devices. This lasted until 2003 and he again left the company seemingly more prosperous than when he began.
PA-Semi was the next stop and he worked again primarily on networking specific SOCs utilizing the PowerPC architecture. So far, by counting fingers, Jim has worked on five major ISAs (Alpha, x86, x86-64, MIPS, and PowerPC). These chips were able to power networking devices with 10 Gb throughput. PA-Semi was then purchased by Apple in 2007/2008.
At Apple Jim was now Director of Platform Architecture and worked with yet another major ISA; ARM. Jim worked to develop several major and successful products with the A4 and A5 processors that have powered the latest iPhone and iPad products from the Cupertino giant. To say that this individual has had his fingers in some very important pies is an understatement.
Jim now rejoins AMD as CVP and Chief Architect of CPU Cores. He will report directly to Mark Papermaster. His primary job is to improve execution efficiency and consistency, as well as implement next generation features into future CPU cores which will keep AMD competitive with not only Intel, but other rising competitors in the low power space. This is finally some good news for AMD as they are actually adding talent rather than losing it. While Jim may not be able to turn the company around overnight, he does look to be an important piece of the puzzle with a huge amount of experience and knowhow with multiple CPU ISA. If there is anyone that can tackle the challenges in front of AMD in the face of a changing world, this might be the guy. So far he has had a positive impact in every stop he has made, and perhaps this could prove to be the pinnacle of his career. Or it could be where his career goes to die. It is hard to say, but I do think that AMD made a good hire with Jim.
