Hello all, This is a first article I try to publish in English version. However, one thing you should know before reading this article is I’m not expert on English so about the grammar some may not correct but I hope this will help you to understand more about this article better than using Google translate or other.

Today we will test in a way that we believe many of us would like to see. We think it might be a good idea to estimate Ryzen 5’s performance by comparing Ryzen R7 1800X with the i7-7700K clock-for-clock and core-for-core. Some of you may not understand what we’re trying to do or what we’re trying to present, but stick around. It’ll be worth your while.

All tests will be done with Ryzen R7 1800X overclocked to 4.0Ghz and core/thread count reduced to 4/8 (half the number of cores and threads is disabled); and i7-7700k underclocked to 4.0Ghz.

Even though both processors are running at the same clock speed with the same core/thread count, each still has a different L3 cache size. The Ryzen R7 1800X has 16MB, while the i7-7700K has only 8MB, and since L3 cache size on either chip can’t be reduced, we believe the Ryzen chip has an L3 cache size advantage.

While this looks like a handicap for the i7-7700K, the objective is to estimate the Ryzen 5 1400X’s performance. As we already know from leaked news everywhere, that SKU will have 4 cores and 8 threads. Theoretically, if the 1400X can be overclocked to 4.0Ghz, its performance shouldn’t be too different compared with our similarly-configured R7 1800X’s performance.

In addition, from today’s tests, we hope to be able to see just how much of a performance gap there is between the AMD’s and Intel’s newest architecture, especially differences in IPC performance when both core/thread counts and clock speeds are the same. We think everyone who fancied owning a Ryzen chip at one point or another would understand what we’re trying to accomplish here, and why.

Except for the processors and motherboards, every piece of hardware used for each setup is the same.

CPU – Memory – VGA : Setup

The RAM speed used is CL15 XMP, but I’d like to make a point that I’m unable to set the same Command Rate (CR) timing for both CPUs because the Ryzen system defaults to 1T and we can’t change it, but on the Intel system it’s running on 2T by default on its XMP profile. I might be asked, why not change the Intel system’s CR timing to 1T? The answer is, because I just want to enable XMP on both systems.

We tried to set RAM timings for both systems but since they are two totally different architectures with different limitations, these were the best settings we could manage.

Also, I decided to underclock the i7-7700K simply because I can’t push the R7 1800X’s clock to 4.5Ghz. The maximum overclock it would allow is 4.0Ghz. And because we handicapped the i7-7700K by underclocking, we also did the same for the 1800X by disabling four of its cores (which amounts to eight threads). For this to be a good comparison between the two different architectures’ IPC (instructions per clock), I think both CPUs must run at the same clock speeds and with the same core/thread counts. You can look at the CPU-Z screenshots to see core and thread count and RAM timings as well.

Test Results

Before continuing with the results, I want to ensure readers that we ran all tests up to three times just to make sure that we minimize all human errors. But if please leave a feedback on our comments section if you see errors in our results data.

SuperPi Mod 1.5 XS – 1M

Let’s start with SuperPi 1M results. It is one of the more popular benchmarking tool used by overclockers for 1M calculations. Here we see that AMD’s R7 1800X was 1 second behind Intel’s i7-7700K when both are running with equal number of cores/threads at the same 4.0Ghz clockspeeds. Percentage wise, the difference between the two CPUs is approximately 11%.

SuperPi Mod 1.5 XS – 32M

The second SuperPi testing was done for calculating 32M. Memory speed greatly affects CPU performance when running these tests. This time, the AMD chip finishes around 1 minute slower than the Intel chip. Percentage-wise this represents a 12% difference between the two architectures, or a 1% gain on the Intel side when it comes to memory speeds.

CINEBENCH R15 – CPU Test

The results of these tests are quite interesting. In single-threaded performance, the 1800X is around 6.8% slower compared to the i7-7700K when both are running at the same clockspeeds, but the AMD chip’s multi-threaded performance is faster than the Intel chip’s by around the same 6.8%.

GeekBench 4

GeekBench 4 was used to measure both CPU’s single-threaded and multi-threaded performance, but results here are quite different compared to those of CINEBENCH R15 because GeekBench measures overall system performance, whereas CINEBENCH R15 only focuses on the CPU. Here we see the i7-7700K beating the R7 1800X in both single- and multi-threading performance by around 12% and 10% respectively. Ryzen’s multi-threaded performance still appears to be slightly better than its single-threaded performance as seen in the results.

RealBench 2.44

Looking at the RealBench 2.44 results we can see that the two systems’ scores were similar, with a less than 1% difference favoring the i7-7700K.

x264 FHD Benchmark v1.0.1 64bit

The FHD Benchmark results were a bit surprising as we expected the i7-7700K to win here, but the Ryzen chip performed 3.2% better.

Handbreak 1.0.3 Benchmark

As we’ve seen in several videos and benchmarks online, the new Ryzen chips performed better than Intel chips in Handbrake. But when the 1800X and i7-7700K are run with the same clock speeds and core/thread counts, we see that the Kaby Lake architecture performs slightly better at around 5% to 6%.

AIDA64 CPU Benchmark

Here we see that the Ryzen chip’s AES score is almost double that of the Kaby Lake’s, but all other tests’ scores suggest it’s still slightly behind Intel’s CPU.

AIDA64 Memory & Cache Benchmark

The results of these tests are quite interesting. The Ryzen chip’s memory was running CR at 1T, which was probably the reason why its memory read speed was slightly better than the 7700K’s. But the latency scores suggest Intel’s CPU is still far ahead compared to AMD’s. In my opinion, memory performance on both sides are similar overall. But still, AMD should address this memory latency problem.

WinRAR 5.2

WinRAR compression and decompression results don’t look good on the AMD side when it comes to both single-threaded and multi-threaded tests. However, looking forward we might see WinRAR releasing an updated version better optimized for Ryzen chips.

3DMark – Time Spy

3DMark Time Spy For this, I think the effect is not much different if a portion of the total score. But the point is obvious difference is that the CPU test 7700K can do much better than about 15% it is considered that the proportion as we can seen since the beginning from other tests

3DMark – Fire Strike Ultra

Fire Strike Ultra both of systems can work out the level is very similar in every part

3DMark – Fire Strike

In the Fire Strike test it will running benching at Full HD resolution in overall score 7700K is slightly high but if we looking at Physics test RYZEN can do a little better

3DMark – Sky Diver

Sky Diver for the effect is considered to be in a similar range. This benchmark test will more focuses on the power of whole system rather than focusing on the power of the graphics card and if we look at the score of Physics test it is similar but 7700K a bit better than just about 8%.

Rise of the Tomb Raider – DX12

For Rise of the Tomb Raider benchmark with average from total it is maybe can say considered to be similar but the 7700K is clearly better than the third Test in Geothermal Valley, The frame came out higher than 15FPS over 1800X and overall resulting 7700K has slightly better also

Tom Clancy’s The Division – DX11

FarCry Primal – DX11

With FarCry Primal after testing new results come out, it is in proportion as we have seen previously tested in the beginning the average frame rate of 1800X is less than approximately 12% this different is still similar from beginning as we have seen

Grand Theft Auto V (GTA V) – DX11

BATTLEFIELD 1 – DX11

Battlefield 1 is a game that I have new tests and the effect that it considered similar but on the average frame rate 7700K can do a bit better about 8%

Memory clock performance

In addition to the power or performance in MHz:MHz and core per core compared today I have to get a little bonus. In terms of the performance of memory I’m a suspect If we have to use the memory more higher clock speed the overall performance will move up very much or not ?

SuperPi Mod 1.5 XS – 32M

GeekBench 4

AIDA64 Memory & Cache Benchmark

WinRAR 5.2

3DMark – Sky Diver

When looking at the results came out, it would be clear that the results have improved on both of systems, the scale increased proportion is similar for each system it not differ in any particular

Final Thought

In the end, we get the answer is more clearly from results as we have seen at all. Even that does not mean it can be confirm in 100%, but it is enough for some guidelines which allow us to assess what has been from what we have or from what we can do right now. From what we can do the test with the MHz by MHz measured in term of face to face as a result, it would make it easier to us for assess what performance or power per MHz of RYZEN’s IPC by estimate

What we can know today from all results we have seen ? Firstly the power or performance of RYZEN’s IPC It will still be behind the Intel 7th Generation or Kaby Lake approximately 10-15% if we have refer from what we have done today and if we do directly proportional to the extrapolation relative in a simple term with previous version of Intel’s Haswell which that we will know that it is effective between Kaby Lake is about 5-10% or maximum around 15%, so maybe we can say for a simple way the performance of RYZEN that close to Haswell CPUs from Intel or comparable to 4th Generation because today we have seen RYZEN is behind Kaby Lake about 10-15% also. If asking to me it was okay ? I would say it’s OKay or good enough for AMD with a good start even it still can not beat or won in competition with Intel but one thing we continue to see the result is the same working of the Multi-Thread in the form of an increase in the proportion of single RYZEN core of AMD still do better than Intel.

Last but not least I think it will allow us to more understand about RYZEN whether performance from CPU core include about Memory performance. But what I think it would make an impressive on all of us would be the result of gaming RYZEN can achieved the same level and from now after we have seen the performance of RYZEN in term of 4 cores 8 threads even if it just a simulation but I think it would make AMD fans or gamers who are waiting for RYZEN R5 more excite because if scale of today between RYZEN 7 1800X but it running with 4 core 8 thread which it simulating to RYZEN R5 it can do a good job it not inferior to much when comparison to Kaby Lake it around 15% from clock by clock so if we looking forward to real RYZEN R5 in a future from leaked news it make us know AMD will have RYZEN R5 1400X model is running with 4 cores 8 threads but we still not know what really clock speed of it, if it coming with clock speed around 4GHz maybe it one of best price and performance because it will have price only 60% of 7700K but in a real world do not forget 7700K is running at 4.2GHz and can boost to 4.5GHz so the scaling of performance will be different from we have seen today also, in addition for today don’t forget also the RYZEN 7 is I have simulating it still have large L3 Cache with 16MB and real RYZEN 5 will only have 8MB same as 7700K if cache size has big impact to performance so performance will more different that today again.

Finally until AMD is released the RYZEN R5 that time we will really know about the real performance of it but at this time, we can only hope the real RYZEN R5 from AMD will can do as we have seen today or closest because today it just simulating.

Enjoy ?
