CCminer(SP-MOD) Modded GPU kernels.

The FPGA doesn't make N multiplications per cycle. It does N hashes per cycle, with N integer > 0 or, in the case of complex algorithms, 1/N.

Yes, but in Randomx the FPGA need to do a memory read per cycle to determine the instruction to be executed so the N hash doesn't apply. Then the new limit is N instructions where N is limited by the number of memory accesses the chip can do per cycle. In older FPGA designs it was normal to have ASIC multipliers you could use to speedup multiplications (f.ex Altera Cyclone IV). The multiplication could also be done in code.

[pallas]

True, but it's also true that you can fill the FPGA with custom made cores each executing RandomX instructions. FPGAs are plenty flexible, much more than GPUs, it only takes much more time to optimise.

[sp_]

With a compiled kernel, the GPU can execute 15000 Randomx Instructions in 15 cycles per hash@2000mhz.

maybe this place has the info. There are rumors about x16rv2 has already ASICS.
Any feedback?

[joblo]

If you don't produce a source it usually means you're starting the rumour.

iBeLink in California is the ASIC provider. Is the source good enough

[Kodaman]

X25X algo is the one and only GPU only algo not for all Nvidia GPUS but also for cards that have 6gb or less because it doesn't require memory hard operations.
For all the Nvidia cards from 1050ti 2 gb up to 1080 ti can all be mined without the fear of ASICS and FPGAS around.
T-Rex has the algo optimised maximum that is why no private miners or no new faster miners for X25X.
Today is the good information day lol

If iBeLink has anounced it it's not a rumour, it's fact. Where did the rumour originate?
Is it your own speculation?

There's nothing in x16rv2 that makes it more technically difficult than x16r to implement on ASIC or FPGA.
It's probably only a matter of time and demand.

T-Rex is slow and not profitable. Bether to mine Beamv2 or Grin.

What about people with 1050tis, 1060 3gbs actually nvidia cards less than 8gbs. What should we mine, which algo and which miner?

[sp_]

Beam can be mined with 3gb cards. gminer.  (windows 7,8.1 or linux)
Grin29 can be mined with 4/6gb cards. gminer (windows 7,8.1 or linux)
for 2gb cards monero  / randomx?

Cool thanks for the tip but what about the windows 10 users?

RANDOMX IS A GOOD QUESTION--

I was just looking at SChernykh's github.  He has coded both CUDA and OpenCL versions for benchmarking RandomX on GPUs.  I compiled and ran the CUDA version on my 1070ti (8GB) rig, and got about 669H/s RandomX per single 1070ti.  I'll try on my 750ti (2GB) rig in a little while.  Both are Linux rigs.

Maybe you could plug the RandomX algo into SuprMiner.  I noticed that none of the commercial, closed source CCminer clones came out with an x16rv2 version until after you modded your SuprMiner source with it.       --scryptr

[pallas]

The difference between x16rv2 and x16r is just tiger, which is a pretty basic algorithm, already available as opensource cuda code on my m7 miner years ago, and as commercial miner used in software supporting my x22i and x25x.

[Kodaman]

Lux is preparing their own flavor of RandomX called RX2. It is said it will favor both gpus and cpus equally.
Miner for RX2 would be needed too...

It's probably only a matter of time and demand.

The difficulty went from 320 to 100 after the hardfork. Raven is profitable on the GPU again...
It also made a message to the Asic devs. Ravencoin is ready to hardfork again at a later stage...

t-rex is not optimized to the maximum.

FPGAs are already mining x16rv2, and porofitability on gpu is down the drain.
It was profitable for a few hours only, just after the fork.

"Down the drain" is a little drastic don't you think? It's just +/- 10% less profitable than XZC
