HIS has launched a new factory overclocked graphics card based on AMD's Radeon HD 7850 "Pitcairn" GPU called the IceQ X^2 Turbo. The new card uses a custom PCB and IceQ X^2 cooler.
The IceQ X^2 cooler uses two 75mm fans to cool an aluminum fin stack that is connected to the copper GPU contact plate with copper heatpipes. The HSF is surrounded by a black shroud. HIS claims that its custom cooler runs at a quiet 28dB when the card is idle.
The HIS HD 7850 IceQ X^2 Turbo is a factory overclocked card. HIS has taken a standard HD 7850 GPU with 1024 stream processors and clocked it at 1GHz, which is a 140MHz overclock over the reference 7850 clockspeed. The card is further paired with 2GB of GDDR5 memory clocked at the reference 1200MHz (4800MHz effective) on a 256-bit bus. An 8-phase VRM keeps the overclocked components fed with stable power. It offers up a single DVI, one HDMI, and two mini-DisplayPort video outputs.
Because of the custom cooler, it should be possible to push the HD 7850 GPU even higher, although exactly how much higher will depend on the individual card.
The HIS IceQ X^2 Turbo does not have any official pricing information yet, but it should be priced somewhere around $220 since the already-available single fan IceQ X Turbo card is currently priced at approximately $210 at online retailers.

NZXT has launched its new Sentry Mix 2 fan controller. Featuring an audio equipment theme, the Sentry Mix 2 fits into a single 5.25” bay. It features a matte black bezel with six glossy black sliders that are recessed into the bezel to ensure compatibility with PC case doors. Below the fan speed sliders are LEDs that can be changed to one of five colors (white, blue, green, orange, red).
The Mix 2 is the successor and replacement of the original Mix fan controller, and it uses a redesigned PCB. The controller has six sliders that are connected to six 4-pin fan outputs. The fan controller is powered by two 4-pin Molex power connectors and can draw a maximum of 180W. Each fan channel can draw a maximum of 30W. The sliders are analog rheostats that are also compatible with PWM controlled fans.
The Sentry Mix 2 comes with a 2 year warranty. The fan controller should be available soon with an MSRP of $29.99. More information can be found on NZXT’s website. As far as fan controllers go, I could see myself using this one as it keeps the LED bling to a minimum.

NVIDIA seems to have completely ignored the economic downturn that has affected so many tech companies and posted gains in both revenue and profit for Q1 2013. The entire PC market may have shrunk by 10% but NVIDIA's profits were up 16.7% compared to 12 months ago, though when looking at GPU sales alone they did see about a 5% decline. Now that NVIDIA has branched out into mobility and HPC however, their total sales are up by 3%. The Register postulates that part of the reason their sales did not decline as much as other manufacturers is their focus on high end GPUs which are immune to the erosion being caused by sales of mobile devices such as tablets. Get the whole set of numbers here.
"In the first quarter of fiscal 2014 ended on April 28, Nvidia's overall sales rose by 3.2 per cent to $954.7m. Big Green was able pull $77.9m to the bottom line, up 16.7 per cent compared to the year-ago period – even while investing in a substantial bump-up in research and development costs – thanks to a shift to higher margin products in both the discrete graphics and Tesla GPU coprocessor lines."

I cannot do it captain! I don't have the not enough power!
We have been discussing the ultra-low power state of Haswell processors for a little over a week and how it could be detrimental to certain power supplies. Power supply manufacturers never quite expected that you could have as little as a 0.05 Amp (0.6W) draw on the 12V rail without being off. Since then, companies such as Enermax started to list power supplies which have been tested and are compliant with the new power requirements.

Above is Corsair's slightly incomplete chart as of the time it was copied from their website, 3:30pm on May 10th, 2013; so far it is coming up all good. Their blog should be updated as new products get validated for the new C6 and C7 CPU sleep states.
The best part of this story is just how odd it is given the race to arc-welding (it's not a podcast so you can't Bingo! hahaha!) supplies we have been experiencing over the last several years. Simply put, some companies never thought that component manufacturers such as Intel would race to the bottom of power draws.

Tagged: tegra 4, nvidia, grid, financial results
NVIDIA has released the results of its first fiscal quarter of 2014. Overall, NVIDIA had a positive first quarter with total revenue of $954.7 million and a net income of $77.9 million. During Q1 2014 the company announced its Grid VCA for enterprise customers and Tegra 4 and Tegra 4i for the mobile market. NVIDIA’s shareholders saw an Earnings Per Share (EPS) of 13 cents, which is up 30% versus the same quarter last year. Interestingly, NVIDIA has announced that it will be returning $1 billion to shareholders through increased dividends and buying back shares.
Q1 2014 is an interesting quarter, as it is up year over year, but down significantly versus the previous quarter (Q4’13). NVIDIA’s Q1’14 revenue of 954.7 million is up YOY 32% from $924.9 million in Q1’13, but down 13.7% from $1.1 billion in the previous quarter. The dip is likely attributable to the fact that its Q1’14 is the quarter after the holiday rush at the end of Q4. Considering it is still up versus last year, the dip versus last quarter shouldn’t be taken as a bad sign. Net income follows a similar pattern, with net income down 53.2% versus last quarter’s $174 million, but up 29% YOY (Q1’13 net income was $60.9 million).
The financial results seem to indicate that NVIDIA is continuing to grow and remain profitable. According to NVIDIA, the company expects to see operating expenses and revenue increase in Q2’14 to $448 million in and approximately $975 million respectively. Further, NVIDIA expects growth to continue throughout 2014 as it launches new Tegra 4(i) SoCs and expands its server/business offerings with its GRID technologies.

Tagged: ddr3, DRAM
It looks like the days of cheap RAM may be coming to a close, not just for the consumer but also for manufacturers of graphics cards, cellphones and anything else with onboard RAM. What began as a slow rise in prices is now becoming a shortage, something guaranteed to bring prices up. In Acer's case they will be out of stock by the end of the month while ASRock stockpiled RAM in this quarter to retain supplies to sell over the coming quarter. As DigiTimes points out, competition is going to become fierce and you can expect both lower supplies and higher prices on the new components you want to buy over the summer.
"Commenting on the issue, Acer chairman JT Wang pointed out that DRAM prices are likely to continue rising as many DRAM makers have switched their production lines to manufacturing smartphone DRAM, leaving insufficient capacity to supply the PC industry. Even If DRAM makers decide to switch back capacity, it will still take about 3-4 months for the process to be completed, Wang said."

Tagged: Volcanic Islands, radeon, ps4, amd
So the Southern Islands might not be entirely stable throughout 2013 as we originally reported; seismic activity being analyzed suggests the eruption of a new GPU micro-architecture as early as Q4. These Volcanic Islands, as they have been codenamed, should explode onto the scene opposing NVIDIA's GeForce GTX 700-series products.
It is times like these where GPGPU-based seismic computation becomes useful.
The rumor is based upon a source which leaked a fragment of a slide outlining the processor in block diagram form and specifications of its alleged flagship chip, "Hawaii". Of primary note, Volcanic Islands is rumored to be organized with both Serial Processing Modules (SPMs) and a Parallel Compute Module (PCM).
So apparently a discrete GPU can have serial processing units embedded on it now.
Heterogeneous Systems Architecture (HSA) is a set of initiatives to bridge the gap between massively parallel workloads and branching logic tasks. We usually make reference to this in terms of APUs and bringing parallel-optimized hardware to the CPU. In this case, we are discussing it in terms of bringing serial processing to the discrete GPU. According to the diagram, the chip within would contain 8 processor modules each with two processing cores and an FPU for a total of 16 cores. There does not seem to be any definite identification whether these cores would be based upon their license to produce x86 processors or their other license to produce ARM processors. Unlike an APU, this is heavily skewed towards parallel computation rather than a relatively even balance between CPU, GPU, and chipset features.
Now of course, why would they do that? Graphics processors can do branching logic but it tends to sharply cut performance. With an architecture such as this, a programmer might be able to more efficiently switch between parallel and branching logic tasks without doing an expensive switch across the motherboard and PCIe bus between devices. Josh Walrath suggested a server containing these as essentially add-in card computers. For gamers, this might help out with workloads such as AI which is awkwardly split between branching logic and massively parallel visibility and path-finding tasks. Josh seems skeptical about this until HSA becomes further adopted, however.
Still, there is a reason why they are implementing this now. I wonder, if the SPMs are based upon simple x86 cores, how the PS4 will influence PC gaming. Technically, a Volcanic Island GPU would be an oversized PS4 within an add-in card. This could give AMD an edge, particularly in games ported to the PC from the Playstation.
This chip, Hawaii, is rumored to have the following specifications:
- 4096 stream processors
- 16 serial processor cores on 8 modules
- 4 geometry engines
- 256 TMUs
- 64 ROPs
- 512-bit GDDR5 memory interface, much like the PS4.
20 nm Gate-Last silicon fab process
- Unclear if TSMC or "Common Platform" (IBM/Samsung/GLOBALFOUNDRIES)
Softpedia is also reporting on this leak. Their addition claims that the GPU will be designed on a 20nm Gate-Last fabrication process. While gate-last is considered to be not worth the extra effort in production, Fully Depleted Silicon On Insulator (FD-SOI) is apparently "amazing" on gate-last at 28nm and smaller fabrication. This could mean that AMD is eying that technology and making this design with intent of switching to an FD-SOI process, without a large redesign which an initially easier gate-first production would require.
Well that is a lot to process... so I will leave you with an open question for our viewers: what do you think AMD has planned with this architecture, and what do you like and/or dislike about what your speculation would mean?

Tagged: audio, headset, Eagle Tech, Urban Zen, Samurai Song
Eagle Tech have certainly chosen a side in the form versus function debate with the visually impressive Arion Urban Zen: Samurai Song headset. While you can use them with a PC to listen to audio these are more aimed at the mobile market as it sports a single jack and the mic will not work on a PC. LANOC were happy with the performance of these headsets for the $50 asking price, with decent audio and a good foldable design, the only warning they offer is that when watching a movie or TV show you might find that conversations sound distant, not an echo so much as sounding as if the speakers are far away.
"I have reviewed quite a few audio products lately each of them have their perks and quirks, but one thing always missing is a bit of customizability, something to set you apart from other users who buy the same product. Eagle Tech has recently began releasing its like or Arion branded products, and amongst those is a headset named the Urban Zen. The Zen headsets come in four different designs and a few different colors. Finally we have some options to set ourselves apart from everyone else. It is nice that we can change things up, but how will the headphones actually perform when it comes down to crunch time?"
