PCI-e 3.0 provides 9% increase in performance in compute tasks for AMD Radeon HD 7970

PCI-Express 3.0 has been here for a little while now, but it has only been with the launch of the PCI-Express 3.0-capable AMD Radeon HD 7000-series that there has been some proper testing. The world's first 28nm GPU to support PCI-e 3.0 is here, people!

PCIe 3.0 increases per-land bandwidth from 500MB/sec to 1GB/sec, this means for an x16 slot, double the bandwidth from 8GB/sec to 16GB/sec. Impressive, but will we see anything close to double the performance? Not now, and not in games. GPU compute tasks do see a difference in performance, however.

 

Improving bandwidth and latency between the CPU and GPU is always a good thing, but for high-performance GPU compute tasks, this is the difference between night and day. AnandTech tested AMD's AES Encrypt/Decrypt sample application. The test bed consisted of an EVGA X79 SLI motherboard, with a BIOS provided by EVGA for the PCIe 3.0 toggle on/off.

 

With this in hand, AnandTech saw a 9-percent increase in performance on the Radeon HD 7970 which told them two things. First, you can get PCIe 3.0 working on a Sandy Bridge-E/X79 board with the Radeon HD 7970, and secondly, PCIe 3.0 will definitely be useful for GPU compute applications.

AMD have updated their A-Series of APUs

AMD have today updated their A-Series line-up of desktop and notebook APUs (Accelerated Processing Units), which include not only speed and performance improvements, but AMD Steady Video update makes this unique feature more compelling than ever. AMD have also included the ability to overclock the APU, so for the first time users can now tune both x86 and graphics settings within the single processor for boosted performance.

The new updated AMD A-Series APUs combine up to four x86 CPU cores with up to 400 Radeon cores, where it delivers DirectX 11-capable, discrete-level graphics and dedicated HD video processing, all on a single chip. The new A-Series APUs deliver a bigger performance punch when compared to the existing A-Series APUs.

LeakedTT: Intel Ivy Bridge desktop chip prices

Intel's Ivy Bridge processor prices have been leaked thanks to CPU World, with another leak today. It looks as though the Intel Core i7-3770K will replace the current Core i7-2700K at the same $332 pricing.

 

TweakTown image news/2/1/21961_01_leakedtt_intel_ivy_bridge_desktop_chip_prices.jpg

 

Core i7-3770K will bt the most expensive, and fastest Ivy Bridge chip at launch. There are three other Core i7 chips that will be released, i7-3770, i7-3770S, i7-3770T. We also have a slew of Core i5 processors, ranging from $184 through to $205. Ivy Bridge-based Core i5 processors will continue the tradition of Sandy Bridge by offering just four physical cores, 6MB of L3 cache and no hyper-threading.

 

The Core i7 processors will include hyper-threading, and 8MB of included cache.

AMD FX-8150 with Microsoft KB2592546 put through "before and after" patch tests

There was a patch that was released by Microsoft last week (KB2592546) for Windows, where it was claimed it would improve performance of systems powered by AMD's latest processor architecture, Bulldozer.

 

TweakTown image news/2/1/21960_09_amd_fx_8150_with_microsoft_kb2592546_put_through_before_and_after_patch_tests.jpg

 

What the patch did, was make the OS aware of the way AMD's Bulldozer cores are structured, so it could effectively make use of the parallelism at its disposal. Microsoft a few days later, pulled the patch. But, this is the Internet.

 

SweOverclockers' had enough time to do a "before and after" performance test of the new AMD FX-8150 processor, with the now pulled patch. The results of SweOverclockers' tests are in the picture above. "tidigare" is before, "nytt" is after, and "skillnad" is change. The chip has been put through a fair amount of tests, some synthetic CPU-intensive tasks, and real-world gaming performance tests.

 

The results are actually, not that good, and this is most likely the reason the patch was pulled.

Intel to intro Core i5-2550K processor

Intel, in it's plot to take over the CPU world, is set to release another unlocked Core i5 processor. It will arrive in the form of the Core i5-2550K and has a retail channel part number of BX80623I52550K and OEM part number CM806230121300, the Core i5-2550K was added to the MDDS database.

The Core i5-2550K will carry the S-spec code SR0QH. Clock speeds are unknown at this time, but CPU World expect it to be 3.40GHz. The chip will be on the LGA1155 package, feature four cores, 256KB L2 cache per core, 6MB shared L3 cache, integrated dual-channel DDR3 IMC, integrated PCI-Express 2.0 root complex and a TDP of 95W.

Intel finally accepts USB 3.0 into their heart, chipsets, will become a standard

The USB Implementers Forum announced this week that Intel's upcoming "Ivy Bridge" 7-Series Chipset, and other Intel chipsets, have achieved, finally, USB 3.0 certification. Intel's Ivy Bridge silicon, which is due to ship in Q2 2012, will have USB 3.0 as a standard feature, for the first time ever. At the moment, it has only been made available on select notebooks and desktops, and requires chips from AMD, or additional chips from NEC, and others.

 

TweakTown image news/2/1/21934_32_intel_finally_accepts_usb_3_0_into_their_heart_will_become_a_standard.jpg

 

General Manager of Intel's Chipset and SoC IP Group, Ahmad Zaidi, said in a statement:

 

SuperSpeed USB certification...helps ensure interoperability and backward compatibility within the broad USB ecosystem.

 

Analysts believe that once USB 3.0 has been baked into Intel's chipset, it will made the standard universal as it can be offered on virtually any PC. Brian O'Rourke, research director for In-Stat, has said:

 

Intel's integration of SuperSpeed USB into its upcoming core logic chipset is critical because it allows cost-conscious PC (makers) to offer the technology at a very competitive price point. Additionally, SuperSpeed USB adoption in PCs is leading to broad adoption in PC peripherals, consumer electronics, and mobile devices.

Intel hearts NFC, enters licensing deal with Inside Secure for NFC

Intel did show off a Medfield-powered tablet at IDF which had NFC tech built in, as well as being partnered with MasterCard, it promises to bring PayPass checkouts to Ultrabooks.

 

TweakTown image news/2/1/21928_27_intel_hearts_nfc_enters_licensing_deal_with_inside_secure_for_nfc.png

 

Intel is now entering a licensing deal with Inside Secure. Inside Secure specializes in contactless payment systems and will be lending its Microread, Secured and Open NFC products to Intel for future chips.

 

NFC should feature in Ultrabooks, and we should see it in any future x86-powered smartphones, too. NFC is looking to become the next pure standard, and with companies like Intel behind it, it gives more confidence to the technology, and its customers.

ARM & GlobalFoundaries show off 2.5GHz+ 28nm Cortex A9 and 20nm test vehicle

GlobalFoundaries will be a name that will be commonly mentioned in 2012, which is something they'll be easily doing if they continue at this pace. They've announced a dual-core Cortex A9 test chip that is built on a 28nm HPP (High Performance Plus) process.

 

This test chip clocks in at 2.5GHz and is said to be capable of higher frequencies. It operating voltage is just 0.85V. Both the frequency and voltage targets are good for a Cortex A9 implementation, but remember, this is just a test chip.

 

TweakTown image news/2/1/21925_24_arm_globalfoundaries_show_off_2_5ghz_28nm_cortex_a9_and_20nm_test_vehicle.png

 

Most companies are expecting to pass the 2GHz mark next year on high-performance 28nm processes, so we should see this by the end of 2012, if not early 2013. We should see these designs in tablets and netbook replacements, with ARM being Windows 8-compatible now.

AMD to release FX-6200, sits at 3.80GHz, with TurboCore speeds at 4.10GHz

AMD launched their AMD FX processor family with just a few units, two eight-core parts (FX-8150, FX-8120), a six-core product (FX-6100), and the quad-core one (FX-4100). But there's now a new processor set to hit the shelves of retailers worldwide, a six-core FX-6200 chip.

 

TweakTown image news/2/1/21915_12_amd_to_release_fx_6200_sits_at_3_80ghz_with_turbocore_speeds_at_4_10ghz.jpg

 

The FX-6200 receives quite the speed boost compared to the FX-6100. The FX-6100 has a stock clock speed of 3.3GHz and 3.90GHz under TurboCore, but the FX-6200 puts its hard hat on and gets onto its Bulldozer with stock clocks at 3.8GHz and a TurboCore speed of 4.10GHz. AMD have a chart which shows that we should expect a 10-percent increase in performance when using MainConcept Convert HD to Flash. I look forward to seeing some real-world, gaming results.

 

Now, if AMD could just find those 800 million transistors that have gone missing...

LeakedTT: Intel's Desktop Platform Roadmap for 2012

To look, or not to look. Ah, come on. You know you're going to take a peek. What does it include? Well, the gist of it, there's not much exciting happening for CPUs (in my opinion) for 2012. The roadmap shows that Intel's superhero, the Core i7-3960K, won't be replaced any time throughout 2012. So, if you have one, you'll feel safe knowing you have the knees that are on those bees throughout the year.

 

TweakTown image news/2/1/21892_04_leakedtt_intel_s_desktop_platform_roadmap_for_2012.jpg

 

But, there will be shifts in all other segments: premium (Core i7), mainstream (Core i5), transactional (Core i3), legacy (Pentium) and value (Celeron and Atom). The biggest change we'll see from Intel in 2012 is the launch of the 22nm-based Socket 1155. There will be a bunch of CPUs released under this new fabrication.

 

These chips include the Core i7-3770K which will sit at the top of the hill, clocked at 3.50GHz, sporting 8MB of cache, 8 threads, and a Turbo Boost speed of 3.90GHz. TDP sits at 77W and does so throughout the entire 22nm-based range. This is down from the 32nm-based chips with TDP's at a max of 95.
