The AMD Ryzen 7 1700X: Power or Bust?

So it is time to dig into the new build: Flammenwerfer! First up is the AMD Ryzen 7 1700X – does upgrading from a 6-core FX6300 to an 8-core 1700X yield any kind of benefit?

…erm…yes?!?

I was not prepared. Not prepared at all for the sheer speed of the new Ryzen architecture. This thing quite literally stomps all over the old FX6300 in every single metric. Even when the FX6300 was overclocked to 4.2GHz. The tests I’ve performed today have been to compare the FX6300 stock-for-stock against the 1700X. Not fair, I know, but it’s all I have to compare.

Don’t believe me? Here – have some Geekbench results:

So, we are looking at a 79% increase in single core performance and a 285% increase in multi-core performance in Geekbench. Some call it a modest performance jump, I call it turning the dial right past 11 and breaking it off the stereo.

In Passmark, the FX6300 scored 6573 points. Not bad for a sub £100 CPU, but pales in comparison to the monstrous score of 14707 that the 1700X puts out.

Let’s do my classice perf/watt test, using TDPs and Passmark scores:

  • AMD Phenom II X4 965 BE: 4222 / 140W TDP = 30.2 points/watt
  • AMD Sempron 145: 803 / 45W = 17.8 points/watt
  • AMD FX6300: 6573 points / 95W TDP = 69.2 points/watt
  • Intel Core i3 4360T: 4599 / 35W TDP = 131.4 points/watt
  • AMD Ryzen 7 1700X: 14707 / 95W TDP = 154.8 points/watt

So there we have it folks! A new performance/watt winner out of my current systems! However, in terms of price/performance – the FX6300 still wins here, more from it’s own low price. Have a look at the Intel X99 parts that the 1700X battles against… well it’s no contest really.

If we look at the 6850k from Intel – that scores a similar number of points on CPUbenchmark.net – but that’s a £620 part. Plus, in most instances, the 1700X has been seen to even make the 6900k look uncomfortable in terms of performance at it’s £1000 price tag.

Cinebench R15 yielded a score of 415 for the FX6300. 1700X? 1549. Yeah, almost 4x the score. At the same wattage. Absolutely nuts.

Gaming is definitely improved – I was getting a lot of stuttering on the old system. Often the FX6300 would be maxed out in games such as Battlefield 1 and Rainbow Six: Siege. Not the case anymore – it feels like I upgraded the GPU too! The improvement in smoothness and minimum frame rates is unbelievable. I will write a more detailed post about gaming performance soon – a hot topic when it comes to Ryzen!

You may be wondering about the CoolerMaster Hyper 212 Plus I am still using. I have the fan profiles set to run the fan at minimum speed at idle (about 700RPM), and that sits the CPU at about 35 degC. This is using the Windows “High Performance” power profile.

You can also see the sensor that has the 20 degC offset applied to it – the “Package” temperature. It is that sensor that AMD uses for XFR (which works nicely – you can see the 3.9 GHz maximum boost). No, I am not running 1.55V through the CPU – that bit is wrong. Nor is it 2.5V. Some of these readings are all over the place at the moment, but this is just to show the idle temperatures.

Load (using the AIDA64 system stability test with CPU, FPU and cache stressing enabled):

So under full load we are looking at just under 60 degC for the “CPU” temperature. The “Package” (minus 20 degC) seems to be sat in the low 70s. Funnily the GPU temperature slowly drops as the fans ramp up (the Asus Strix would be in passive cooling mode!). We are looking at a fan speed of about 1300 RPM with the profile I have set up – not silent but not at all loud.

I have not tried to overclock the chip with the Hyper 212 – nor will I. I will save the overclocking until I get the AIO – the fan speed and temperature would go a bit silly if I did try it on the 212.

So I had best summarise the experience so far. In comparison to my old FX6300, it wipes the floor with it. It’s not the best value chip on the block – but I paid for performance, and that’s exactly what I got – and the price is not bad for the speeds you get. Intel, you had better be afraid right now. Bravo, AMD – you took your sweet time but it’s paid off in my book. 10/10.

Up next – the motherboard: the ASRock Fatal1ty X370 Gaming K4!

AMD Ryzen is here!
