*results should be taken lightly & with a pinch of salt for now, as Ryzen CPU's are not available yet and these results are compiled from what benchmarks have become available (with screenshots of CPU-Z), and prices leaked from various websites that had them for sale before taking them down (screenshots also provided on links below)

Ok, so 'beats Intel' is a bold statement to use when in reality (according to various early benchmarks) 'clock-for-clock' they are on-par, but the numbers do show a favourable percentage increase for AMD with the CPU-Z benchmarks, but when compared 'price-for-price' (R5-1600X vs i5-7600K) then AMD have a 50% performance advantage! AMD have recently shipped tests samples of their new Ryzen CPU's to select websites for benchmarking, the latest benchmarks to hit the web are for AMDs R5 1600X which is an unlocked 14nm, 6-core, 12-thread, 16Mb cache CPU which runs at 3.3Ghz..boosting to 3.7Ghz.

Price over Performance:
The AMD R5 range is meant to compete with Intel's i5 range in terms of price, the top R5 chip (1600X) is supposedly going to sell for $259, which is just a shade more than the i5 7600k Kaby-Lake CPU at $243, while the AMD chip might be 'supposedly' 7% more in cost, it is 50% faster in terms of performance when compared to the i5-7600K.

$1000 Intel CPU Performance in $250 AMD chip!:
While the R5-1600X is AMD's top 'middle-of-the-range' CPU, its only 3.5% slower than intel's $1000 8-core/16-thread i7-6900K Extreme chip and about 16% slower than their $1700 10-core 6950X behemoth when running at the same clock speed, this is just one benchmark off CPU-Z, but its another good indicator that Ryzen is going to be an excellent chip, especially if they do sell at the prices they've been seen for sale at.

Used to compare the benchmarks the AMD R5 is shown alongside the intel Kaby-Lake i5 & various other generation i7's, obviously Quad vs Hexa isnt a fair match so Single Thread performance is measured and compared (as well as multi-threaded tests just for good measure), shown below are both the 1600X and 6700K with scores amended to reflect 'clock-for-clock' speeds both at 3.7Ghz (1600X) and 4.2Ghz (6700K)... (bare in mind the AMDs can be over-clocked when they are released). Also I have guestimated AMD R7 multi-thread performance within the same benchmark by increasing the R5 result by 33.33% to account for a core count increase from 6 to 8, and another the same with 8% extra to account for an increase to 4.0Ghz to match the Intel at 4.0Ghz.

Results of *Single Thread* tests in CPU-Z (highest-to-lowest):

AMD R5-1600X @ 4.2Ghz  = 2,143 (Ryzen)
**estimated @ +13.5% to 4.2Ghz from 3.7Ghz
Intel i5-7600K @ 4.2Ghz   = 2,134 (KabyLake)
Intel i7-6700K @ 4.2Ghz   = 2,118 (Skylake)

AMD R5-1600X @ 3.7Ghz  = 1,888 (Ryzen)
Intel i7-6700K @ 3.7Ghz   = 1,858 (Skylake)
Intel i7-6850K @ 3.8Ghz   = 1,835 (Skylake)
Intel i7-6900K @ 3.7Ghz   = 1,784 (Skylake)
Intel i7-6950X @ 4.0Ghz   = 1,659 (Broadwell-E)
Intel i7-4700K @ 3.9Ghz   = 1,527 (Haswell)

AMD FX-8370 @ 4.3Ghz    = 1,232 (PileDriver)

Results of *Multi-Thread* tests in CPU-Z (highest-to-lowest):

AMD R7 ***** @ 4.0Ghz   = 18,063 (8-core Ryzen CPU @ $490)**estimated, R5 3.7Ghz + 2 cores @ +33.33% (+ 8% to 4.0Ghz)
AMD R7 ***** @ 3.7Ghz   = 16,725 (8-core Ryzen CPU @ $490)**estimated, R5 3.7Ghz + 2 cores @ +33.33%
Intel i7-6950X @ 4.0Ghz   = 16,119 (10-core Broadwell-E CPU @ $1700)
AMD R5-1600X @ 4.2Ghz  = 14,239 (6-core Ryzen CPU @ $259)
Intel i7-6900K @ 3.7Ghz   = 12,980 (8-core Skylake CPU @ $1100)
Intel i7-5960X @ 3.5Ghz   = 12,892 (8-core Haswell-E CPU @ $1000)
AMD R5-1600X @ 3.7Ghz  = 12,544 (6-core Ryzen CPU @ $259)
Intel i7-6850K @ 3.8Ghz   = 10,872 (6-core Skylake CPU @ $572)
Intel i5-7600K @ 4.2Ghz   = 8,361   (4-core KabyLake CPU @ $243)
AMD FX-8370 @ 4.3Ghz    = 7,632   (8-core PileDriver CPU @ $179)

Results taken, interpreted & compiled from test results and data from these sites: Link 1 : Link 2 : Link 3 : Link 4

As you can see from these (and other) results that AMD's Ryzen is definitely going to be a game changer, providing the test results are true and the sale prices are correct (who knows), also that is just one benchmark from CPU-Z, other benchmarks have shown AMD's circa $500 8-core/16-thread R7-1800X @ 3.4Ghz is only 9% slower than Intel's $1000 8-core/16-thread i7-6900K @ 3.7Ghz...BUT.. the 6900K is 9% faster in clock speed, so in that respect & in that benchmark they are neck in neck, either way I think we can look forward to Ryzen release in March, hopefully it should help drive down CPU prices overall..meaning we the consumers get more bang for our buck!

I share your excitement, wouldn't it be great to finally have some actual competition for Intel in the higher CPU's.

I have seen the unofficial benchmarks too and its easy to get enthusiastic about Ryzen, especially when you see the prices they are publishing.  I hope to upgrade my main PC this year and it can only be a good thing AMD are back.

We need to see some official testing and price confirmation, also hope they are actually available to buy ;)
