AMD FX-8150 Tested with Latest Windows Hotfixes, Still No Improvement

German tech website TweakPC did a before-after comparison of applying Microsoft's recently-released KB2645594 + KB2646060 Windows updates, which intend to improve performance of systems running AMD FX processors, by improving the way in which the OS deals with Bulldozer cores, using a top-of-the-line FX-8150 processor. The reviewer put FX-8150 through synthetic tests such as AIDA64 (CPU benchmarks, FPU benchmarks), Cinebench 11.5, MaxxPi (multi-threaded PI calculations), WPrime, Twofish AES, 3DMark (Vantage and 11), ComputeMark; and some real-world tests such as WinRAR, Resident Evil 5, and Battleforge. Barring Resident Evil 5, where the patched FX-8150 produced 4% higher performance and WinRAR, where it produced 3% higher performance, there were no significant performance gains noticed.

Christmas Special: The PC Technology of 2011

Welcome to the TechPowerUp 2011 PC technology Christmas special. We hope that you will enjoy reading it while tucking into your turkey, Christmas presents and a little too much wine... In this article, we go through the technology of 2011 that has had the most significance, the most impact and was generally the most talked about. It's not necessarily the best tech of 2011 which is the most significant though, since lemons can be just as significant as the ground-breakers in how they fail to deliver - and the backlash that goes with it.

January: Intel Sandy Bridge i5 & i7

Released on January 9th, the new Intel Core i5 & i7 processors were based on Intel's second generation Core architecture built on a 32 nm production process (HEXUS review). They included an IGP (Integrated Graphics Processor) physically on the same piece of silicon along with HyperThreading. These new dual and quad core processors soundly beat all previous generations of Intel processors in terms of processing performance, heat, power use, features and left AMD in the dust. Therefore, Intel badly needed some competition from AMD and unless you have been living under a rock, you will know how that turned out in October with the launch of Bulldozer. Sandy Bridge was a sound win and is generally considered to be the only architecture worth considering at this point. The i5-2500K is currently at the sweet spot of price/performance. It comes at a stock speed of 3.3 GHz, but typically overclocks to an amazing 4.5 - 5 GHz with a decent air cooler and without too much difficulty in getting there. Models in the budget i3 range were released at various times later. See this Wikipedia article for details.

AMD FX 8150 with Microsoft KB2592546 Put Through 'Before and After' Patch Tests

To the surprise of many, last week, Microsoft rolled out a patch (KB2592546) for Windows that it claimed would improve performance of systems running AMD processors based on the "Bulldozer" architecture. The patch works by making the OS aware of the way Bulldozer cores are structured, so it could effectively make use of the parallelism at its disposal. Sadly, a couple of days later, it pulled that patch. Meanwhile, SweClockers got enough time to do a "before and after" performance test of the AMD FX-8150 processor, using this patch.

The results of SweClockers' tests are tabled below. "tidigare" is before, "nytt" is after, and "skillnad" is change. The reviewer put the chip through a wide range of tests, including synthetic CPU-intensive tests (both single and multi-threaded), and real-world gaming performance tests. The results are less than impressive. Perhaps, that's why the patch was redacted.

AMD Bulldozer Threading Hotfix Pulled

Since we reported on the AMD Bulldozer hotfix, The Tech Report reports in an updated post, that the Bulldozer threading hotfix said to improve performance of the processor, has been pulled:
We've spoken with an industry source familiar with this situation, and it appears the release of this hotfix was either inadvertent, premature, or both. There is indeed a Bulldozer threading patch for Windows in the works, but it should come in two parts, not just one. The patch that was briefly released is only one portion of the total solution, and it may very well reduce performance if used on its own. We're hearing the full Windows update for Bulldozer performance optimization is scheduled for release in Q1 of 2012. For now, Bulldozer owners, the best thing to do is to sit tight and wait.
It will be very interesting indeed to see how this much maligned processor benchmarks after the fully developed patch is released. It's true, actually attempting to download the hotfix and agreeing to the licence terms, at the moment, one is lead to a page that shows it as unavailable.

AMD 'Bulldozer' gets an Update from Microsoft.

Today Windows updater may have brought "Bulldozer" users a little surprise. A hotfix that increases the AMD flagship processors performance. As this "hotfix" is bleeding edge news any benchmarks have yet to be seen but this confirms Windows 7 was in fact hampering “Bulldozer” from performing at 100% in all prior benches. What percentage it was previously performing at has yet to be determined. Here is a small snippet from the Hotfix release notes.
This article introduces an update that optimizes the performance of AMD Bulldozer CPUs that are used by Windows 7-based or Windows Server 2008 R2-based computers. Currently, the performance of AMD Bulldozer CPUs is slower than expected. This behavior occurs because the threading logic in Windows 7 and in Windows Server 2008 R2 is not optimized to use the Simultaneous Multithreading (SMT) scheduling feature. This feature was introduced in the Bulldozer family of AMD CPUs.

AMD Releases Catalyst 11.5b Hotfix Update

AMD was a little too early in May with its monthly Catalyst driver release, with the Catalyst 11.5 WHQL reaching the web as early as 9th May (typically monthly Catalyst updates are released after the 24th). On the same date, AMD also released its first hotfix update for the Catalyst 11.5, the 11.5a Hotfix Update, which packed a number of game-specific performance improvements. Today, the company released its second such update for the month, with Catalyst 11.5b Hotfix.

The update is rushed in to fix a number of issues found with the recently-released game, Brink. It also fixes a number of non-gaming application issues, particularly related to media decoding. In the process, the driver also brings with it a number of game-specific performance improvements, games including Civilization 5, Dead Rising 2, Fallout 3, Mafia 2, NBA 2010, ShenGuiChuanQi, Starcraft 2, Warcraft III, World of Warcraft, and Dirt 3.

AMD Catalyst 11.5 WHQL, 11.5a Hotfix Driver Suite Released

It's not even 15th of the month, and AMD already released its monthly update of the Catalyst driver suite, which is normally reserved for the last week of the month. Catalyst 11.5 WHQL doesn't come with any performance enhancements as such, but apparently AMD found that a certain feature-enhancement in HydraVision was important enough to warrant a WHQL release. HydraGrid feature found in HydraVision is now aware of custom (user-created) Bezels. There's now also a "Automatic Grid" option that aligns to the user defined Eyefinity display layout.

The rather dull WHQL release is backed by a Hotfix release that comes with a lot more outstanding issues. Catalyst 11.5a Hotfix update includes fixes concerning quality of videos GPU-transcoded from H.264 clips to MPEG2 Blu-ray video, intermittent cursor lag, performance and quality enhancements for the upcoming game Brink, and flickering noted by Radeon HD 6600 series graphics cards with DDR3 memory running in DX9.

Catalyst Hotfix 71310 Restores Visual Elements at Expense of Performance

AMD had released an updated hotfix to its ATI Catalyst 8.10 drivers the other day, with hotfix 71310. It succeeded hotfix 70517 for the said version of Catalyst. Hotfixes specific to certain games, are intended to selectively improve hardware performance and/or visual quality. When AMD released the older hotfix for version 8.10 of Catalyst, it aimed to improve performance in general. It was later found by keen observers, that the hotfix manipulated with visual elements of the game in an attempt to gain performance. A popular example of this, was noted in the "lost rocks" issue in Far Cry 2, where the hotfix 70517 caused the texture and/or geometric loss of certain rocks along a track from a scene, presumably reducing load on the graphics processor(s).

With hotfix 71310 issued yesterday, AMD seems to have fixed the issue. Expreview put the hotfix to test, where it was found that the "lost rocks" issue was fixed. The larger issue was of the driver interfering with visual elements the game has to offer. The fix however, came at the expense of performance. Expreview used a test-bed consisting of Core 2 Extreme QX9650 CPU, ATI Radeon HD 4870 graphics, 2x 1 GB of DDR3 1066 MHz memory, all seated on an ASUS Striker II Extreme motherboard, running Windows Vista 32-bit operating system. The testers used Driver Sweeper to make sure a new variant of the driver installed on a purged environment. Testing Far Cry 2 revealed that the issue was addressed, but at a performance loss. The frame-rate dropped from 48.12 fps to 43.20, which is roughly a 10% loss in frame-rate.

AMD Issues Far Cry 2 Hotfix for Most ATI Radeon Video Cards

Odd enough, AMD has just issued a hotfix for the yet to be released PC game title Far Cry 2. The patch is meant to be used for the Radeon X1000, HD 2000, HD 3000 and HD 4000 series cards to improve the performance of Far Cry 2 in DirectX 9 and DirectX 10. Both single and CrossFire compatible systems will benefit from it. The hotfix download package includes both the Display Driver and Catalyst Control Center. The hotfix can be downloaded by clicking on this link here. After all this might be a smart move for AMD/ATI. The official launch date for Far Cry 2 is October 24th, and the game will launch simultaneously on the PC, Xbox 360 and PlayStation 3. Now ATI owners will be prepared and hopefully won't have problems running the game when it is released.Source: AMD
