Before we get to gaming, we want to see exactly where memory performance results differ, and there is no better tool than SiSoft’s SANDRA 2017. SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an complete information & diagnostic utility in one complete package. It is able to provide all the information about your hardware, software and other devices for diagnosis and for benchmarking. In addition, Sandra is derived from a Greek name that implies “defender” or “helper” – a PC Wonder Woman.
There are several versions of Sandra 2017, including a free version of Sandra Lite that anyone can download and use. It is highly recommended! SiSoft’s Sandra 2017 SP4 is the very latest version, and we are using the full engineer suite courtesy of SiSoft, with quite a few improvements over earlier versions of Sandra. It will benchmark and analyze all of the important PC subsystems and even rank your PC and make recommendations for improvements.
We run the very latest SANDRA memory intensive benchmark tests. Here is the chart summarizing the results of our memory speed testing.
We are next featuring a brand-new-to-BTR test suite, AIDA64.
AIDA64 is the successor to Everest and it is an important industry tool for benchmarkers. Its memory bandwidth benchmarks (Memory Read, Memory Write, and Memory Copy) measure the maximum available memory data transfer bandwidth. AIDA64’s benchmark code methods are written in Assembly language, and they are extremely optimized for every popular AMD, Intel and VIA processor core variants by utilizing the appropriate instruction set extensions. We use the Engineer’s version of AIDA64 courtesy of FinalWire. AIDA64 is free to to try and use for 30 days.
The AIDA 64 Memory Latency benchmark measures the typical delay from when the CPU reads data from system memory. Memory latency time means the time is accurately measured from the issuing of the read command until the data arrives to the integer registers of the CPU.
The Team Group 3200 MHz results:
The Team Group 3333 MHz results:
The HyperX 3333 MHz results:
The Team Group 3400 MHz results:
Here is the summary of the multiple AIDA64 memory benchmarks in a single chart that were harvested from the more detailed individual memory tests:
Faster memory scores higher. Let’s look at PC Mark 8 next to see if the benchmarks that are run reflect memory speed increases.
PCMark 8 has an Creative test which actually uses real world timed benchmarks which include web browsing, video group chat, photo, batch, and video editing, music and video tests, and even mainstream gaming. The PCMark 8 Storage Test doesn’t test the CPU or memory, and there is almost no difference from increasing memory clock speeds.
The Team Group 3200 MHz scores 6828 overall and the individual tests are shown in the captured image below.
Now we increase the clocks by 133 MHz to 3333 MHz to match the HyperX Predator clocks.
The Team Group 3333 MHz scores 6841 which is a micro increase over 3200 MHz. There is some very slight speed-up but gaming is unaffected.
Let’s look at the HyperX Predator DDR4 at 3333 MHz,
The HyperX 3333 MHz scores 6913 with much of the increase from gaming FPS. We would consider this result an outlier although it is not far off.
Next we look at the overclocked Team Group DDR4’s results.
The Team Group 3400 MHz scores again incrementally higher at 6865 than at 3333 MHz just like it did over 3200 MHz.
Here are the overall results for easy reference:The results of running the Creative benchmark in PC Mark 8 are rather inconclusive but they do show very slight increases in the overall score as the memory speeds are increased by 133 MHz than by another 67 MHz for the Team Group Night Hawk kit.
Let’s look at our next synthetic test, RealBench.
RealBench is a benchmarking utility by ASUS Republic of Gamers which benchmarks image editing, encoding, OpenCL, Heavy Multitasking, and spits out an overall score. Some of these tests are affected by CPU and memory speeds.
The Team Group 3200 MHz scores 184435.
The Team Group 3333 MHz scores 186867, a solid increase coming with the +133 MHz increased memory clocks.
The HyperX 3333 MHz scores 187268 which is a little higher than the Night Hawk memory at the same clocks.
The Team Group 3400 MHz scores 187568 to edge out the Predator RAM, and another jump over the 3333 MHz speed grade.
Here are the individual tests summarized. Just like with PC Mark 8, the individual results are inconclusive.
Next we benchmark using Cinebench.
CINEBENCH is based on MAXON’s professional 3D content creation suite, CINEMA 4D. This latest R15.038 version of CINEBENCH can test up to 64 processor threads accurately and automatically. It is an excellent tool to compare both CPU/memory and graphics OGL performance. We are going to focus only on the CPU which is given is cb, and higher is always better.
The Team Group 3200 MHz scores 1534 cb.
The Team Group 3333 MHz scores incrementally higher at 1539 cb.
The HyperX 3333 MHz scores 1534 cb which only matches the Team Group memory at 3200 MHz.
The Team Group 3400 MHz scores 1544 cb which is a further small speed up over the score at 3333 MHz.
Here is the summary chart. HyperX Predator at 3333 MHz only matches the Night Hawk at 3200 MHz, but the slight performance increase with memory speed scaling is evident even over a limited 200 MHz range.
On to Wprime for number crunching.
WPrime is a multi-threaded benchmark which can show the differences in IPC between CPUs and faster memory will make a difference. Here are the tests, and we choose to calculate 1024 million digits and 32 million digits showing multiple runs.
The Team Group 3200 MHz achieves its best scores of 7.425 sec for 32M and 234.305 for 1024M.
The Team Group 3333 MHz achieves its best scores of 7.421 sec for 32M and 233.988 for 1024M.
The HyperX Predator 3333 MHz achieves its best scores of 7.463 sec for 32M and 234.741 for 1024M which makes it slower than the 3200 MHz Team Hawk equipped PC.
The Team Group 3333 MHz achieves its best scores of 7.407 sec for 32M and 233.915 for 1024M which are incrementally faster than the same memory at 3200 MHz.
Here is a Wprime comparison chart with the fastest numbers from each set of runs charted.
If you increase the memory speed, the CPU can crunch numbers a little faster. Let’s look at game-related benchmarks
The Team Group 3200 MHz scores 65.17 FPS.
The Team Group 3333 MHz scores 65.39 FPS.
The HyperX 3333 MHz scores 65.25 FPS
The Team Group 3400 MHz scores 65.47 FPS, again a very tiny incremental increase over 3333 MHz as it is over 3200 MHz.
We see tiny increases with this physics-based demo that demonstrates that increasing the CPU and memory speeds can produce faster results. Here is the summary chart:
Let’s look at Star Swarm Demo next.
The Team Group 3200 MHz scores 120.98 FPS.
The Team Group 3333 MHz scores 123.30 FPS.
The HyperX Predator 3333 MHz achieves 134.04 FPS, higher than the Team Group memory at 3333 MHz.
The Team Group 3400 MHz reaches the very highest average framerate at 152.49 FPS.
We see an increase in FPS in this demo by increasing the memory clocks. Here is the summary chart that shows a steady increase in the framerates as the Night Hawk’s memory clocks are increased:
On to real gaming!
Below is the summary chart of 9 games some of which are sensitive to scaling with increasing CPU speeds and possibly with increasing memory clocks using a stock GTC 1080 Ti Founders Edition.
