Egzotična neka dama Tajland?

Tocno, 6/6 sa 25% visim clockom i boljim ipc-em spada u klasu iznad..

 Samo ako ti ubaciš monitor od 120Hz :)

Jedni te isti drobe isto i tako u krug, pa opet. 

i opet....

 Niti se borim, a jos manje gubim zivce na ista i zapravo se slazem sa ostatkom koji si napisao. Stvar je u tome da je ovo forum na koji ljudi osim nekakvog informiranja dolaze ubiti vrijeme, iznjeti svoje misljenje i malo se prepucavati sa drugima, osim toga dobar dio nas vec "poznaje" jedan drugog na nekoj forumskoj razini pa time sve skupa ima dodatnu car. 

59 fps je gore nego rak. Ko kaze da nije - roditelji ga se trebaju sramiti

Lol, mogli su ti rec bez monitora da igras, dodje na isto...

 Ja si uvijek stavim frame limiter na 59 fps-a, tako da se forumskim stručnjacima počne štucati.

Ali sad šalu na stranu, najslabiji procesor na ovom HW unboxed testu, 1500X, je imao prosječno 111 fpsova i minimalno 85 na 1080p (ajmo biti realni i izbaciti 720p), i to isključivo u CPU zahtjevnim igrama. To je skoro duplo više od ovih magičnih 60, a procesor još nije ni klokan (dakle išla bi i a320 ploča za 420 kn) za što se zna da donosi još barem 10-15% na ovom procesoru, što bi ga dovuklo do npr 120.

Tako da su danas i ajmo reći jeftiniji procesori sasvim dostatni za bilo kakav gaming (pustimo specijalce sa 240 hz, igre koji oni igraju će raditi na 240 fps na bilo kom modernom procesoru), treba se koncentrirati na grafičke i ove spike su prelijevanje iz šupljeg u prazno...

A da ne spomenem 1440p i 4k što bi po meni polako trebao biti standard.

 I slabiji procesori su dovoljnio za 60 fps od jednog 1500x, ako igras na 100+ hz monitoru pucas na fluidnost i tu je vazan "headroom" koji ti cpu daje tj da nemas ucestale dropove i sto bolje 1% low fps, idealno bi bilo kad bi imao uvijek iznad 144 fps.

Postat ce standard 1440p 144hz isto tako.

 A sta mislis zasto sam linkao dva videa? Zato sto u prvom imas klokani 1600x na 4.0 GHz dok je 8600k na stock, na drugom videu je 8600k kloknut pa ima jos manji pad fps-a. 

P.S. Taj video koji uporno linkate je komedija, jedini je gdje ryzen vodi u POBG-u od mora ostalih videa...

 Svi argumenti u real life upotrebi su minus za kafu, a ni za igre nemaš argumente jer su podjednaki.Hvataš se za nekih par fps-a razlike gdje je jedan bolji u ovoj a drugi u onoj igri. Popij tu kafu.

U 9 od 10 performance testova 1600 je brži na stocku. S obzirom da u godinu dana odigram sat vremena, uz trenutno jeftinije ploče 40-ak € B350 od Z370 , ne vidim kako 8400 može dati najviše uloženo dobiveno. Možda za tri mjeseca kad dođu ploče, i možda samo za igrače, i možda samo za one sa 120Hz+ monitorima na 1080p, jer na 60Hz ili 1440p nije bitno.

Zna se namjena ryzena, on sluzi kako bi i sirotinja mogla imat respektabilne cinebench score-ove. Power to the poor!

Vjerovatno je brzina memorije bitna ali ipak threadripper korist quad channel memoriju što daje mnogo vece brzinu u odnosu na dual iste brzine.

Sve je stvar percepcije. Nisu to problemi sa memorijom nego poboljšanja. Dakle, po defaultu radi tako i tako, ako povećaš frekvenciju memorije radi bolje. Dakle, AMD ima poboljšanja uz bolju memoriju, dok Intel nema. Intel je poboljšan u startu :)

Šalu na stranu, ovaj post ispod stvarno dobro objašnjava što se događa. Infinity fabric ovisi o brzini frekvencije. Ukratko, 3200 sa low-latency (LL) je brže od 3600 sa CL16. 

The extra bandwidth in GB/s above 3200 doesn't really help that much for extra performance. Kits that are rated at higher frequencies and can be used as you have to keep latencies low by dropping the kit to run slower but tighter. 4000mhz kits are not worth spending the money on unless you can turn the binning to your advantage, running the ram at lower frequencies but with much tighter timings, given that 4000mhz kits are rated at CL18 and CL19 they are not actually that fast to start with compared to the 3200c14, 3600cl15 or CL16 kits making the slower kits a much better buy. When 4500 becomes an available product then the ultra high kits will give Ryzen better performance as their native latency will be around 8ns but they will initially be cost prohibitive.

One thing that you didnt mention is that all ram has a native latency that you can calculate from the timings and it can be helpful in deciding what direction to take in setting up you system memory. The formula is (CAS setting/Kit MTs rating) x 2000 or you can use (CAS/actual frequency Mhz) x 1000 ad the DDR4 kits are double data rate kits. The actual frequency that the Infinity Fabric is using is half of what the kit states. the 2000 takes this into account so you don need to remember to divide the kit speed in two.

18/4000 x 2000 = 9 ns
16/3600 x 2000 = 8.89ns
14/3466 x 2000 = 8.08ns
14/3200 x 2000 = 8.75ns
12/3200 x 2000 = 7.5ns

You can see that your kit at 3466 is better than the kit at 3600c16 or 4000c18. If you can get your system to boot and run with your Ram kit set at 3200 CL12 settings, you should find even more performance in gaming.

If you divide the result by the cas setting, it will tell you how many nanoseconds each cycle tales. The infinity fabric transfers data between CCX modules, memory controllers and PCIe controllers at the rate of 32 bytes per cycle. Remember that if you want to convert everything to nanoseconds to investigate the component parts of system latency, Cache memory on Ryzen is running at CPU frequency and not ram frequency so the number of cycles cache memory takes to get a 4ns L2 cache latency is different from the number of cycles it takes for the system RAM to do something in 4ns. When you measure system latency the path is L1+L2_L3 cache then the time it tales the system ram for do its stuff based on these timings.

You may find though that as latency decreases with really tight timings, there is a cross over point where multithreaded performance multiplier efficiency over single core performance starts to drop off. The key is to find the best compromise between latency and multi thread performance. The idle period of time where the CPU primary thread on a core is queued up waiting for memory access because of latency gives the secondary SMT thread access to CPU time to do its process work. That is why the Ryzen chips mutlithreaded performance tends to scale better over their single core scores than Intel chips do. Intel hyper thread efficiency is about 25% vs Ryzen getting almost 50%. You can check the multiplier using the single and multi core scores in cinebench.
