G.Skill DDR3 2200 MHz C7 PI memory review -
DDR3-2200 with Core i7 860/870 processor - Performance
Memory Read test
Okay so we are back at synthetic testing. Here we have the read performance of the memory at that 2200 MHz clock frequency. Obviously we needed to overclock the PC to achieve this memory data rate.
As you can see, overclocked (dual-channel memory) we got performance over 20.000 MB/sec (!), stunning in a dual-channel configuration, yes absolutely stunning. Once we lower the memory divider to JEDEC 1333 CAS 9 we still get horrendous good performance though thanks to the increase baseclock.
Memory Write test
Write performance then -- A Phenom II processor will perform roughly in-between 6500 and 7000 MB/sec -- with sharp timings you'd take it to roughly 8000 MB/sec. Intel's latest Core i5 and I7 offerings will offer roughly 10.000 MB/sec at JEDEC 1333 MHz at Dual-channel configuration.
Core i7 Bloomfield Nehalem processors with triple channel will vary a little depending on model/QPI but maxes out at roughly 14.000 MB/sec again based on JEDEC timings and frequency of 1333 MHz -- overclocked or with fast DIMMs these would rock out as well.
G.Skill in dual-channel mode reaches a confusing 17.000 MB/sec at 2200 MHz. Now again, the increase baseclock really pushes the memory. But yeah, that's beating triple channel memory alright.
Let's transcode some video ..
Transcoding over the CPU or GPU
We recently added another benchmark to the test-suite. It's MediaShow Espresso. The fun thing about this video transcoder is that it can utilize the GPU to assist it with the transcending process. However, you can also solely use the CPU, making this a very interesting benchmark and you can check out behavior of CPU transcoding AND GPU transcoding all in one test.
Below you can find the first results of this new test. In this test we transcode a 200 MB AVCHD 1920x1080i media file to a 1280x720P MP4 binary.
Here again we have the processor at roughly 4 GHz with increased base clock in order to achieve the high memory data rate. Though this is more of a raw compute test, the faster memory does make a difference. Where it can really help though are games. Let browse to the next page.
G.Skill designed another 8GB low voltage DDR3 kit (2x 4GB) that can be set at 1600 MHz yet still run a CAS latency of 7. And that is truly interesting because the denser the ICs get, the higher latency typically gets.
G.Skill 2x4GB CL7 1600 MHz Trident DDR3 review
We feel that more memory is rather important, and in that trend memory manufacturers have started to increase the density of DIMM modules. Where 1 and 2GB DIMM modules have been the standard, we now see very good progress in 4 GB DIMM modules. Today we\'ll do things a little different, G.Skill designed a 8GB low voltage DDR3 kit (2x 4GB) that can be set at 1600 MHz yet still run a CAS latency of 7. And that is truly interesting because the denser the ICs get, the higher latency typically gets.
G.Skill Flare DDR3 2000 MHZ C7 AMD kit review
We test and review the G.Skill Flare DDR3 2000 MHZ C7 AMD kit. These kits are optimized for AMD platforms preferably with the new six-core X6 processors, and in specific some ASUS motherboards. The kit we'll be testing today obviously comes from that series and is a 2,000MHz CL7-9-7-24 1.65V 4GB (2GBx2) DDR3 kit with its latest Flare heatsinks.
G.Skill Phoenix PRO 120GB SSD review
The SSD tested today once again is the Phoenix series from G.Skill. After we tested their 100GB Phoenix SSD (which received a very positive review) G.Skill instantly requested if we would like to review the 120GB PRO model. Both drives pretty much are the same thing, same controller ... The 100GB Phoenix uses Samsung memory though but the trick is that there is 20GB extra volume space available on the new 120GB Pro (compared to the 100GB model) for nearly the same price. A new Firmware for the SandForce 1200 based controller that is inside this 120GB model simply reserves less NAND flash memory for its data-compression scheme. As a result the overall write performance could be a tiny bit slower, but only a few percent as best. It however will give you 20 GB more space to play around with at the same price. And since price per GB is everything in the land of SSDs -- this certainly is a significant for any vendor and for you as an end-user.
