Tagged: mineral oil, Intel
Intel has been dunking servers in oil for the last year and found the practice to be both safe and effective. Ironically it has been almost a year since we played around with mineral oil cooling – and when we did – we did not want to upgrade or fix anything. Intel agrees.
Intel inside, slick mess outside.
Often cooling a computer with a radiant that is not air focuses on cooling a handful of specific components and leaving the rest exposed to air. Gigabyte in their recent live presentation showed how the company reduced waste heat on the motherboard as it delivers power to the CPU as the latter likely receives more cooling than the former. With mineral oil you are able to more efficiently cool the entire system by immersing it in a better coolant than air.
This still makes Ken wake up in a cold sweat… is what we convince ourselves.
After a full year of testing servers, Intel has decided that oil immersion cooling should be utilized by more server hosts to cut costs over traditional air conditioning. In their test they used heat sinks which were designed for air and dunked them pretty much unmodified into the mineral oil dielectric. Apart from the mess of it – Intel engineers always carried cleaning cloths just in case – Intel seems to only sing praise for results of their study.
Of course Intel could not help but promote their upcoming Phi platform which you may know as the ancestor of Larabee.
Now the real question is whether Intel just wanted to shamelessly plug themselves – or whether they are looking so closely at alternative cooling solutions as a result of their upcoming Phi platform. Will we eventually see heat dissipation concerns rear their heads with the new platform? Could Intel either be sitting on or throttling Phi because they are waiting for a new heat dissipation paradigm?
Could be interesting.
Ah, IDF – the Intel Developer Forum. Almost every year–while I sit in slightly uncomfortable chairs and stare at outdated and color washed projector screens–information is passed on about Intel's future architectures, products and technologies. Last year we learned the final details about Ivy Bridge, and this year we are getting the first details about Haswell, which is the first architecture designed by Intel from the ground up for servers, desktops, laptops, tablets and phones.
While Sandy Bridge and Ivy Bridge were really derivatives of prior designs and thought processes, the Haswell design is something completely different for the company. Yes, the microarchitecture of Haswell is still very similar to Sandy Bridge (SNB), but the differences are more philosophical rather than technological.
Intel's target is a converged core: a single design that is flexible enough to be utilized in mobility devices like tablets while also scaling to the performance levels required for workstations and servers. They retain the majority of the architecture design from Sandy Bridge and Ivy Bridge including the core design as well as the key features that make Intel's parts unique: HyperThreading, Intel Turbo Boost, and the ring interconnect.
The three pillars that Intel wanted to address with Haswell were performance, modularity, and power innovations. Each of these has its own key goals including improving performance of legacy code (existing), and having the ability to extract greater parallelism with less coding work for developers.

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.
