Not too long ago the release of a new processor family meant a noticeable improvement from the previous generation and the only question was how to upgrade, not if you should upgrade.  Like many other things, that has passed on into the proverbial good old days and now we need reviews like this one published by [H]ard|OCP.  Is there any noticeable performance difference between the two chips outside of synthetic benchmarks? 

The test systems are slightly different as the memory has changed, the 7700K has 2666MHz DDR4 while the 2600K has 2133MHz DDR3; both CPUs are clocked at 4.5GHz however.  Their results show actual performance deltas in productivity software such as HandBrake and Blender, justifying the upgrade for those who focus on content creation.  As for gaming, if you have no GPU then you will indeed see performance increases; but nothing compared to buying a GPU.

"There are many HardOCP readers that are still running Sandy Bridge CPUs and have been waiting with anticipation of one day upgrading to a new system. One of the biggest things asked in the last month is just how the 2600K stacks up against the new 7700K processor. So we got hold of one of our readers 2600K systems and put it to the test."

Intel Allegedly Working to Replace Sandy Bridge

Subject: Processors | January 2, 2017 - 10:33 PM |
Tagged: sandy bridge, Intel

OC3D is claiming that Intel is working on a significantly new architecture, targeting somewhere around the 2019 or 2020 time frame. Like AMD’s Bulldozer, while there were several architectures after the initial release, they were all based around a set of the same basic assumptions with tweaks for better IPC, reducing bottlenecks, and so forth. Intel has also been using the same fundamentals since Sandy Bridge, albeit theirs aligned much better with how x86 applications were being developed.

According to the report, Intel’s new architecture is expected to remove some old instructions, which will make it less compatible with applications that use these commands. This is actually very similar to what AMD was attempting to do with Bulldozer... to a point. AMD projected that applications would scale well to multiple cores, and use GPUs for floating-point operations; as such, they designed cores in pairs, and decided to eliminate redundant parts, such as half of the floating-point units. Hindsight being 20/20, we now know that developers didn’t change their habits (and earlier Bulldozer parts were allegedly overzealous with cutting out elements in a few areas, too).

In Intel’s case, from what we hear about at the moment, their cuts should be less broad than AMD’s. Rather than projecting a radical shift in programming, they’re just going to cut the fat of their existing instruction set, unless there’s bigger changes planned for the next couple years of development. As for the unlucky applications that use these instructions, OC3D speculates that either Intel or the host operating systems will provide some emulation method, likely in software.

If the things they cut haven’t been used in several years, then you can probably get acceptable performance in the applications that require them via emulation. On the other hand, a bad decision could choke the processor in the same way that Bulldozer, especially the early variants, did for AMD. On the other-other hand, Intel has something that AMD didn’t: the market-share to push (desktop) developers in a given direction. On the fourth hand, which I’ll return to its rightful owner, I promise, we don’t know how much the “(desktop)” clause will translate to overall software in two years.

Right now, it seems like x86 is successfully holding off ARM in performance-critical, consumer applications. If that continues, then Intel might be able to push x86 software development, even if they get a little aggressive like AMD did five-plus-development-time years ago.

Tagged: sandy bridge, Ivy Bridge, linux, ubuntu 13.04

The news might be heavily slanted towards Haswell right now but for Linux users improvements to Sandy Bridge and Ivy Bridge GPU drivers are still a major focus.  As there have been updates to the drivers as well as to Ubuntu, Phoronix felt it was time to revisit the performance metrics of the graphics on a Core i3 3217U.  While they did see improvements when you compare it to previous driver versions it seems that there is still some work to do as the performance still lags behind the Win7 driver.

"After yesterday's Intel Sandy Bridge and Ivy Bridge Linux graphics comparison using the very latest Intel Linux graphics driver, here are new benchmarks using the latest Windows and Linux Intel OpenGL graphics driver. Facing competition this morning is Microsoft Windows 7 Pro x64 and Ubuntu 13.04 with its updated open-source stack."

The P8Z77X-I Deluxe is ASUS' high-powered answer to the small form factor crowd. Through some unique design decisions and an upright daughter-board, ASUS was able to cram a full 10-phase digital power delivery system into this board without sacrificing any other integrated components. It's nice to see a manufacturer step up and design a mini-ITX board in the same vein as its full-sized counterpart. We put the board through our normal gamut of tests to see how well this mighty Mini-ITX board sized up with its full-sized brethren. At a retail list price of $219, the P8Z77-I Deluxe needs to prove its worth against the full sized boards.

Ivy Bridge versus Sandy Bridge in a power consumption showdown

Subject: Processors | September 18, 2012 - 05:49 PM |
Tagged: sandy bridge, Ivy Bridge, Intel

iXBT Labs wanted to see how the two most current generations of Intel processors compare when running identical tasks.  To put the processors under maximum load they used Linpack and Furmark as well as looking at video playback.  In the case of the Furmark and Linpack+Furmark tests it might have been nice to see a power versus performance metric, as better performance on the benchmarks could make a slightly less power hungry CPU even more attractive.  However the video playback is a great example of what you can expect in the way of power draw as no one wants a faster processor to play their movie back at an increased speed, a 2 hour movie should take 2 hours to play.  That makes the second metric a little more valuable for those on battery power.  Take a quick peek at their 2 page article here.

"We measured consumed power and energy consumption of four configurations based on the same testbed and four different CPUs belonging to two platforms: Intel Core i7-2700K (Sandy Bridge) and Intel Core i7-3770K (Ivy Bridge), Intel Core i5-2400 (Sandy Bridge) and Intel Core i5-3450 (Ivy Bridge)."

New Low-Cost 35W Ivy Bridge Processors Coming

Subject: Processors | September 4, 2012 - 02:46 PM |
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?

VR-Zone took a processor from each of Intel's last three architectures, clocked them all to 4.7GHz and started benchmarking.  By clocking them all the same you get to see a better comparison of the performance of the various architectures, although the motherboard chipset does introduce a variable into the performance results.  As well, the Ivy Bridge Core i7-3770K is an engineering sample and so may not perfectly reflect the performance of the final retail product.  Drop by to see how these chips compare in synthetic benchmarks.
