This is one of the bugs that exist in the recent AMD drivers for the 5700 XT. It may also exist for other AMD cards with this driver or for this card on the 20.4.2 or 20.5.1 driver. This one was very difficult to isolate. I enabled the “Video Replay” feature in the AMD driver panel. A few days later many of my favorite games started to “hitch or stutter” during random events in the games I play. One of my favorite games that worked flawlessly before the change is Kingdom Come: Deliverance. I spent some time searching for any solutions.
I tested temperatures and enabled logging for temperature events, I looked at SMART data for my NVMe drives, I ran the typical sfc /scannow. I checked DirectX diag log files. Spent a lot of time searching for the proverbial needle in the hay stack that changed my performance.
RESULT: Disable the Video Replay in the AMD Video Driver panel and test your results. This solved my problems in Kingdom Come: Deliverance and in other titles on my system.
In both of the above benchmarks the following items are identical:
Nvidia Video driver
Evga GTX260 core 216 GPU
4G of RAM
Intel X25-M SSD
The following items are different:
DDR2 RAM for the QX9650 benchmark.
DDR3 RAM for the i5 660 benchmark.
The QX9650 is using an Evga 780i FTW motheroboard.
The i5 660 is using an ASUS P7H55-M Pro motherboard.
The differences in the benchmark results are negligible. The i5 660 Processor is able to perform within one half of one percent of the QX9650.
Provided the Intel Core 2 Extreme Edition QX9650 processor is an older processor. But it is a processor that was one of the fastest Intel had ever created 2 years ago when it released.
If you are in the market to buy or build a new computer, the Intel i5 660 makes a very compelling argument for high performance. Of all things, it is also very energy efficient. The processor tends to run very cool even under duress. My testing shows a top temperature of 35 degrees Celsius with stock cooling in a CoolerMaster 690 II advanced case with the stock fans. If you are using an older processor that is not as powerful as the QX9650 you should see significant performance gain. Bottom line. This system has more bang for your proverbial dollar than any other system you can buy or build. I build and sell i5 660 based systems starting at $1195 plus shipping. The Intel Core 2 Extreme Edition QX9650 processor cost $1000 on sale typically.
The Intel H55 chipset does NOT support dual video cards OR RAID. If you are interested in those features you will need to step up to an Intel P55 chipset based motherboard to enable them. The extreme performance crowd will want SLi or Crossfire support that this system can NOT provide. Even if you use a P55 chipset motherboard you are limited to two video cards running at 8x performance each. To obtain the full x16 performance on multiple video cards simultaneously you have to step up to an X58 socket 1366 motherboard and processor.
This benchmark was for Lame and the results indicate that the i5 660, i5 661, and the i7 870 all tied for first when encoding audio from wav format to mp3 format. They all outperformed the i7 980x. Lame is obviously not SMP for more than 2 cores.
I said something to this effect back in September of 2009.
Long before Tom’s Hardware and/or Nvidia mysteriously came to the same independent conclusion on their own. Sometimes emulation is indeed the best form of flattery.
Today I received the Official Western Digital announcement for the new VelociRaptor 10,000 RPM 600G SATA 6G/s drive. Sounds impressive. If we were limited to mechanical drives, this one definitely would be the one to have for performance. The problem is, we are not limited to mechanical drives. Solid state drives are readily available. The Intel X25-M produces much faster results using a SATA 3G/s interface than the new VelociRaptor drive does using a 6G/s interface. Mechanical drives are wonderful for economical long term storage. The VelociRaptor is far from economical. The 300G model is selling for approximately $200 on Amazon. When compared to a 1TB Western Digital OEM Caviar Black at $100, that is a fairly hefty price for the performance. I recommend using a mechanical hard drive as your “long term” storage of choice. I also recommend using an SSD for your operating system, and key performance hungry applications. ANY SSD will outperform the fastest VelociRaptor any day of the week in any I/O performance test.
Recently I have fielded many inquiries related to building the fastest servers available.
So, in reply. I am publishing the list of criterion I adhere to. These are requirements for the server systems that I build and sell for production web or file servers. My standards of quality and moral values in this regard will not waiver based on the lure of easy wealth or time constraints. If I do not have the time to focus the requisite attention on building a server right, it will not be built. I will not cut corners on quality. I build each server by hand. I build each system in Long Beach, California. All sales are direct from Evanscomputers.com. If you find a system for sale with my name on it elsewhere, it’s either used (not likely), or an imitation.
1. Stock and reasonably available production parts. Using prototype parts is out of the question. Engineering samples are legitimate if you can later reproduce the result with a production part.
2. Standard clock speeds. Overclocking may be a wonderful option for a gaming system. When you plan to use the system as a production server, that has to be online and operational 24×7 365 days of the year ( or as close to that as possible ) overclocking is not an option. Not to mention that it voids your warranties for the processor and motherboard in most cases.
3. A reproducible production grade build of the system. If you spend 25 hours modifying the system and can not reproduce that with every server you manufacture for sale to your clients, it does not apply.
4. An off the shelf operating system. If you modify the operating system for the benchmark results, and you can not or will not do so for your production systems, it would not apply. If it is a tuning or selection of components that you can and do reproduce for a production system, that’s perfectly acceptable. See rule 2.
5. Reproducible results of the benchmark. If you perform the benchmark once and can not reproduce the results using the same criterion again, using the same production grade system, it is not a valid benchmark.
6. Test tools that are readily available and produce consistent results. I personally prefer Phoronix Test Suite. The tests are standardized and produce consistent results for the same versions of the software. There are other test suites available that provide consistent reliable benchmark results.
7. A system that is configured correctly and securely for a production server environment. SELinux or equivalent enabled in enforcing targeted mode at the very least.
All that said, when following the above guidelines, I build the fastest servers that exist. Faster than Dell 2, 4, 8 or even 16 core servers. Faster than Fujitsu-Siemens Dual Xeons. Faster than even HP Proliant servers. I do not build the least expensive servers available, only the best.
I am never the fastest for every benchmark. I am usually the fastest for Super-Pi and Apache-Build benchmarks. I do get bested on occasion. Currently I am the fastest for Super-Pi to 1 Million digits using the criterion stated above with results that are consistently reproducible and published at Phoronix. Dealer inquiries are not welcome here. Comments and your business are! : )
I have often read that Fedora Logical RAID has better performance characteristics than a “BIOS” or “FAKE” RAID. That may be true in some cases. Today I dispelled that myth in regards to Nvidia BIOS RAID0 versus Fedora Logical RAID0. The test results were identical. Results were obtained with the latest Fedora 12 updates applied, and EXT4 was the format of the file systems. Note that in all but one test of the series, the Nvidia C55 based ASUS P5N-E SLi E8400 system using a standard WDC 5000AAKS running Fedora 11 with an EXT3 partition outperformed an Evga 780i FTW QX9650 system using two WDC 5000AAKS in RAID0 AND using an Intel X25M SSD. Check the results at the link at the top of this article.
I now have the 3 fastest benchmarks for compiling Apache web server version 2.2.11. The server I build that out performs everything else is the ECC® Sabre, which I build on a case by case basis. The results are published at Phoronix
If you are interested in ordering an ECC® Sabre or any of the other servers I build by hand in the United States of America, feel free to contact me at jaguar07 at evanscomputers.com or visit my web site
