The Low Cost Sandy Bridge-E

In the conclusion to my original story looking at the performance characteristics of the Sandy Bridge-E platform, I wrote this:

I am most interested in the Core i7-3930K (as I think most of you will be), but we are going to have to wait a bit to see if we can get performance and power results for that part.

Well good readers, I am here with that information!  After getting my hands on the Core i7-3930K processor that makes up the other 50% of the available options for the X79 chipset motherboards, I can definitively say that THIS is the processor you want.  Unless you are crazy-go-nuts rich.  

With a clock speed only about 2.5% lower than its bigger brother yet a price that is 44% lower, the LGA2011 socket definitely has its enthusiast favorite. 

The Sandy Bridge-E Summary

I am not going to bother reprinting everything that we discussed about the new Sandy Bridge-E processor architecture, the X79 chipset and platform changes here though if you haven't read about them before today, you should definitely take a look at my earlier article

Here is a quicker summary:

The answer might surprise you, but truthfully not a whole lot has changed.  In fact, from a purely architectural stand point (when looking at the x86 processor cores), Sandy Bridge-E looks essentially identical to the cores found in currently available Sandy Bridge CPUs.  You will see the same benefits of the additional AVX instruction set in applications that take advantage of it, a shared L3 cache that exists between all of the cores for data coherency and the ring bus introduced with Sandy Bridge is still there to move data between the cores, cache and uncore sections of the die.

Turbo Boost technology makes a return here as well with the updated 2.0 version in full effect - there are more steppings in scalability on this part than on the Nehalem or Westmere CPUs.

Our collection of videos comparing the AMD A8-3850 Llano APU to the Sandy Bridge-based Core i3-2105 have been very popular.  We thought we would wrap up 2011 with one final video that looks at the integrated graphics solutions on both processors in five of the top games released in 2011.  Here is what and how we compared them:

  • Batman: Arkham City - 1920x1080 - Low
  • Portal 2 - 1920x1080 - Very High
  • Battlefield 3 - 1366x768 - Low
  • Skyrim - 1920x1080 - Low
  • Modern Warfare 3 - 1920x1080 - High

Not to give away the secret but...

Ivy Bridge should be here by the spring

Good news for those of you who have been waiting to upgrade in the hopes that Ivy Bridge will be arriving on time.  It seems your patience has paid off but you will have to wait a while longer before you can get your hands on Intel's next tick.  You can look forward to more PCIe 3.0 lanes, just like those who've jumped onto the new Sandy Bridge E chips and a bump on the GPU portion of the chip.  X-bit Labs doesn't have any pricing for the new chips, but they do list all of the models you will be able to buy.  One thing you should note are the impressive TDPs, they may not count as low power CPUs but they're certainly lower than other Intel and AMD chips currently on the market.

"Intel Corp. has notified its partners about its decision to introduce of its next-generation code-named Ivy Bridge processors in the second quarter of 2012. Previously the company planned to release the Core i 3000-series central processing units (CPUs) for desktops in March - April timeframe, which left a possibility to unveil the chips in the first quarter."

Ivy Bridge Delayed Further Into 2012

Subject: Processors | December 1, 2011 - 11:50 AM |
Tagged: Ivy Bridge, Intel, delayed, 22nm

Although Intel’s latest Sandy Bridge successor, Ivy Bridge, was slated for a January 2012 launch, the situation is now looking more bleak. According to these slides over at BSN, Intel is delaying Ivy Bridge until at least April. While the top end Core i7 3770 Ivy Bridge processor might be available as soon as Q2 2012, it is also the most expensive part, and usually not the one that the majority of enthusiasts are waiting for. Rather, the important processors to watch for are the mid range and overclocker-friendly Core i5 series which will be available in Q3 2012 at the earliest if the current road-map holds true. The i5 3550 part may come out in Q2 2012 along with the top end i7 CPU; however, the majority of i5 processors will be released as soon as Q3 2012.

Further, the budget Core i3 Ivy Bridge parts are in the same boat as the i5 processors, with at least one (possibly) becoming available along with the top end Core i7 part in Q2 2012 and the rest slowly trickling out over the remainder of the year. While it is generally the case that the top end processor(s) are released first, followed by the lower end and less expensive parts, the delay has pushed back a April release for some of the budget parts to a Summer release. Needless to say, it is less than ideal for those consumers eagerly waiting for certain chips to go on sale. Not to mention that for those adventurous few that were willing to pay top dollar for the top end i7 chip this January now have to wait even longer.

INTC_BusinessRoadmap_689.jpg

The delay is likely due to Intel wanting to get as much money as possible out of the Sandy Bridge platform, and the lackluster launch of AMD’s Bulldozer products. Intel is likely taking the extra time to refine the new chipsets and the PCIe 3.0 support (that is also not technically rated for PCIe 3.0 speeds, sort of (heh)). On the other hand, Bright Side Of News speculates that the delay may be in part due to various retirements throughout the company requiring more development time in addition to needing more time to flesh out the graphics drivers for the GPU portion of Ivy Bridge processors.

Were you hoping for an Ivy Bridge upgrade early next year? Because of the further delays, will you spring for a top end Sandy Bridge system or wait it out for Ivy Bridge despite the money burning a hole in your pocket? As someone that is still rocking a 1156 system, I was hoping to skip Sandy Bridge and go for Ivy Bridge (I seem to love near-end-to-life sockets); however, with the delays I’m not sure what I’ll be doing now.

Intel Processors Power The Majority of Top 500 Supercomputers, Looking to Expand With MIC Solutions

This year saw the 40th anniversary of (the availability of) the world’s first microprocessor- the Intel 4004 processor- and Intel is as strong as ever. On the supercomputing and HPC (High Performance Computing) front, Intel processors are powering the majority of the Top 500 supercomputers, and at this years supercomputing conference (SC11) the company talked about their current and future high performance silicon. Mainly, Intel talked about its new Intel Xeon E5 family of processors and the new Many Integrated Cores Knights Corner Larrabee successor.

220px-Intel_xeon_e7.jpg

The Intel Xeon E5 is available now.

The new Xeon chips are launching now and should be widely available within the first half of 2012. Several (lucky) supercomputing centers have already gotten their hands on the new chips and are now powering 10 systems on the Top 500 list where the 20,000 Xeon E5 CPUs are delivering a combined 3.4 Petaflops.

According to benchmarks, Intel is expecting a respectable 70% performance increase on HPC workloads versus the previous generation Xeon 5600 CPUs. Further Intel stated that the new E5 silicon is capable of as much as a 2x increase in raw FLOPS performance, according to Linpack benchmarks.

Intel is reporting that demand for the initial production run chips is “approximately 20 times greater than previous generation processors.” Rajeeb Hazra, the General Manager of Technical Computing of Intel’s Datacenenter and Connected Systems Group, stated that “customer acceptance of the Intel Xeon E5 processor has exceeded our expectations and is driving the fastest debut on the TOP 500 list of any processor in Intel’s history.” The company further reiterated several supercomputers that are set to go online son and will be powered by the new E5 CPUs including the 10 Petaflops Stampede computer at the Texas Advanced Computing Center and the 1 Petaflops Pleiades expansion for NASA.

While Intel processors are powering the majority of the world’s fastest supercomputers, graphics card hardware and GPGPU software has started to make its way into quite a few supercomputers as powerful companion processors that can greatly outperform a similar number of traditional CPUs (assuming the software can take advantage of the GPU hardware of course). In response to this, Intel has been working on it’s own MIC (Many Integrated Core) solution for a few years now. Starting with Larrabee, then Knights Ferry, and now Knights Corner, Intel has been working on silicon that using numerous small processing cores that can use the X86 instruction set to power highly parallel applications. Examples given by Intel as useful applications for their Many Integrated Core hardware includes weather modeling, tomography, and protein folding.

Knights Corner is the company’s latest iteration of MIC hardware, and is the first hardware that is commercially available. Knights Corner is capable of delivering more than 1 Teraflops of double precision floating point performance. Hazra stated that “having this performance now in a single chip based on Intel MIC architecture is a milestone that will once again be etched into HPC history” much like Intel’s first Teraflop supercomputer that utilized 9,680 Pentium Pro CPUs in 1997.

What’s interesting about Knights Corner lies in the ability of the hardware to run existing applications without porting to alternative programing languages like Nvidia’s CUDA or AMD’s Stream GPU languages. That is not to say that the hardware itself is not interesting, however. Knights Corner will be produced using Intel’s Tri-Gate transistors on a 22nm manufacturing process, and will feature “more than 50 cores.” Unlike current GPGPU solutions, the Knights Corner hardware is fully accessible and can be programmed as if the card is it’s own HPC node running a Linux based operating system.

More information on the Knights Corner architecture can be found here. I think it will be interesting to see how well Knights Corner will be adopted for high performance workloads versus graphics cards from Nvidia and AMD, especially now that the industry has already begun adapting GPGPU solutions using such programming technologies like CUDA, and graphics cards are becoming more general purpose (or at least less specialized) in hardware design. Is Intel too late for the (supercomputing market adoption) party, or just in time? What do you think?

Running Cool 'n' Quiet under Linux with AMD

Tagged: amd, bulldozer, cool 'n' quiet, Turbo Core, linux, fx-8150

AMD's Cool'n'Quiet feature, which lowers your CPU core frequencies when they are not under heavy usage has been around for a while, but Phoronix though it was time to revisit the Linux support for this feature and Turbo Core as we have a brand new architecture to test.  They fired up the FX-8150 again, running under Ubuntu 11.10 with the Linux 3.1 kernel and started benchmarking.  Their results show that AMD's power saving features are still working well under Linux, better when using single threaded applications than with multi-threaded but still worth enabling for those who want lower heat production and energy consumption.  It is hard to say how much you will save on power though, as the software Phoronix used to measure, fam15h_power, never budged from the 125W mark even when the system was pulling less power from the wall.

Video Perspective: AMD A8-3850 vs Core i3-2105 on Modern Warfare 3

Subject: Graphics Cards, Processors | November 21, 2011 - 10:00 PM |
Tagged: video, sandy bridge, mw3, modern warfare 3, Intel, APU, amd

There is little denying that Call of Duty: Modern Warfar 3 is a success; I think it sold like 19 billion copies on the first night.  Something like that.  So, as we have done quite a bit in recent months, we wanted to see how our processor-graphics based solutions compared to each other in the title.  We recently took a look at how Battlefield 3 performed and we had a lot of great feedback on that post - so let's try this again!  

Luckily for gamers (or not, depending on your point of view), MW3 is pretty light on graphics hardware.  We did our testing at 1920x1080 with the following quality settings:

mw3-2.png

With 2x anti-aliasing enabled and most quality settings turned up to their highest options, the game still looked pretty good during our testing.  No, it's no Battlefield 3, but very few titles are.

mw3-1.png

Both systems come in with a total cost of about $450 with the Core i3-2105 and A8-3850 at the center of each configuration. 

As you might guess, the integrated graphics on the AMD Llano APU outperforms the Sandy Bridge graphics, but by how much?  Check out the video for all the details!

Heard of the AMD VISION Engine?

Tagged: AMD VISION Engine, amd, fusion, APU, steady video

The AMD VISION Engine is the name that AMD is using to describe the new features they are offering for users of their GPUs, APUs and those with both.  One example is the AMD Steady Video feature that Ryan and Ken showed off in July.  That is not all, this encompasses the hybrid Crossfire that exists in Llano laptops with discrete GPUs straight through to support for 30bit colour depth (aka 10bit per channel, 10 bit per pixel) and the GPU accelerated Flash. 

If you are interested in getting more from your APU then head to the AMD VISION site to download their driver package, think of it as a Catalyst with benefits.

Intel's $1000 flagship CPU exists again, in the form of the 3960X Extreme Edition

Subject: Processors | November 14, 2011 - 03:12 PM |
Tagged: Intel, sandy bridge-e, x79, 3960x extreme edition

It has been a while since Intel has released a CPU at $1000, which has felt a little strange as historically they've had a flagship processor in that price range.  Sangy Bridge E spells the return to this price point with the Core-i7 3960X Extreme Edition CPU.  The basic stats will make you drool, 6 cores and 12 threads of 32nm, 130W TDP CPU with a base clock of 3.3GHz, Turbo speed of 3.9GHz and 15MB of shared cache.  The benchmarks however leave something to be desired; certainly it is faster than the original Sandy Bridge but it does not leave the competition eating its dirt.  Single GPU gamers probably won't even notice a change from previous chips, however with the extra power of the 3960X paired with the amazing amount of PCIe lanes available on the X79 series of motherboards, multi-GPU users may benefit much more from this chip.  That still doesn't change [H]ard|OCP's final comment about this chip, "Sandy Bridge E, maximizing BitTorrent ratios, one desktop at a time."

Sandy Bridge-E is just what you expect

Introduction

It has been more than three years since Intel released the first Core i7 processor built around the Nehalem CPU architecture along with the X58 chipset.  It quickly became the platform of choice for the enthusiast market (gamers and overclockers), and remained in that role even as the world of processors evolved around it with the release of Westmere and Sandy Bridge.  Yes, we have been big supporters of the Sandy Bridge Core i7 parts for some time as the "new" platform of choice for gamers, but part of us always fondly remembered the days of Nehalem and X58. 

Well, Intel shared the sentimentl and this holiday they are officially unveiling the Sandy Bridge-E platform and the X79 chipset.  The "E" stands for enthusiast in this case and you'll find that many of the same decisions and patterns apply from the Nehalem release to this one.  Nehalem and X58 was really meant as a workstation design but the performance and features were so good that Intel wanted to offer it to the high-end consumer as well. Sandy Bridge-E is the same thing - this design is clearly built for the high-profit areas of computing including workstation and servers but those that want the best available technology will find it pretty damn attractive as well.

But what actually makes a Sandy Bridge-E processor (now going with the Core i7-3xxx model naming scheme) different from the Sandy Bridge CPUs we have come to love since it was released in January of this year?

The Sandy Bridge-E Architecture

The answer might surprise you, but truthfully not a whole lot has changed.  In fact, from a purely architectural stand point (when looking at the x86 processor cores), Sandy Bridge-E looks essentially identical to the cores found in currently available Sandy Bridge CPUs.  You will see the same benefits of the additional AVX instruction set in applications that take advantage of it, a shared L3 cache that exists between all of the cores for data coherency and the ring bus introduced with Sandy Bridge is still there to move data between the cores, cache and uncore sections of the die.
