spacemit k3 clarifications

yoshi_fp36 đã đăng vào 31, Tháng 5, 2026, 15:29

technically a 16 core but it's not that great.

default: 8 cores. due to isa incompatibility, since X100 implements Rv64H.

next is a100 sucks for anything but feeding the npu, so the A100 is actually a 4 core programmable npu in disguise. even spacemit doesnt want you to run normal apps on "AI cores".

10mb l2 cache but the cache itself is already LLC and 30 cycle L2 latency on X100 is subpar compared to eg. gracemont. vector throughput is also not impressive by any means.

"Quad issue out of order", yet can't seem to reach A76 performance. 8 X100 cores sometimes has an edge over Pi 5, and one would usually compare it to a RK3588, which kinda fits the description. to be honest the X200 is going to reach skylake performance, but it's 6-wide, and it's not near even X2 performance (which isnt even peak 6-wide technology...)

the battle of the absolute giants

yoshi_fp36 đã đăng vào 27, Tháng 5, 2026, 9:44

as i have come to ts conclusion...

lets fight

on the left side

it's the greatest cpu money can buy

Intel(R) Xeon(R) Platinum 9282 Processor core ultra X9 388H ultra whatever i don't care. SHUT UP

right side

its the new one in town, jsut wake up

rockchip... (?) rk3688 12-core

last time we decided to do a quick "Comparison" of X9 388h vs spacemit k3... you know how that went. so time to get something that's at least competent...

focusing on the memory side first. rk3688 comes out on top with lpddr6, but is equally sided if lp5 was used. i don't have high hopes for latency and cpu bandwidth though.

gpu: as this is the least competent part of the x9 388h, i'll pass. OH WAIT, You remember who I am right? XJXIIJWIEIQJIJJ!OFOOADR!! OF COURSE IM GONNA MAKE USELESS COMPARISONS... LETS GO BOISSS

x9 388 Gpu: mali magni >2.0 TFLOPS

Rk36XX GPU: INTEL ARC BXXX > 7.0 TFLOPS

RK36XX is straight up mogmaxxing x9 388 in raw compute alone and it can even play games... how wonderful

Lets focus on the main party: the cpu.

cpu demonstration table is down below.

Core X9 3838588248219321499533124759132H Rockchjp RK36294994192491532042032425 Rockchjp RK36294994192491532042032405
Ultra performance mogmaxxing cores 4X coigar Cove (4 cores), Intels latest specint2k6 architecture, > 2.2 specint 2K17/ghz, > 18 specint2K6GHz* (listen up, A730? you thought HIGH PERFORMANCE means catching up to Cortex-X2? LOLOLLLLL, you're still stuck in ancient clock speeds ) , P cores, born from lion cove, node shrink of lion cove., 5.1 Ghz can't even add a c0rtex-x967 core just for the sake of it!!! why, rockcjp? you're getting absolutely outmogged by 3838588248219321499533124759132H... just do it rockchjp i don't believe in you. now get out as this is the low end chip, i don't mind them. WRONG. DEAD WRONG. ONE SHOULD HAVE A C0RTEX X4. GET OUT.
Low performance efficiency cores 4X darkmont lpe, node shrink of skymont. easily mogmaxxes the rk36294994192491532042032425 everyday... 4x c1 nano/a530, arms latest e-waste architecture, > 0.8 specint 2K17/ghz, > 6 specint2K6GHz* (arm should be ASHAMED of selling this in the BIG 27) , up to 2.XX Ghz 6X c1 nano/a530, arms latest e-waste architecture, > 0.8 specint 2K17/ghz, > 6 specint2K6GHz* (arm should be ASHAMED of selling this in the BIG 27) , up to 2.XX Ghz. R0CKCJP SHOULD BE ASHAMED OF SPAMMING SIX OF THESE E-WASTE CORES AS SOME FORM OF ANNOYANCE IN THEIR LATEST PRODUCTS. SHOWS HOW THEIR RELATIONSHIP WITH THE A5X LINES NEVER ENDED, THEY'RE JUST PUTTING A7X for SMOKES AND CAN'T BE COMPETENT ENOUGH TO PUT AN X-c0RE.
efficiency cores 8X Darkmont, node shrink of skymont. , 3.8 GHz,Intels latest densemaxxing architecture, > 2.0 specint 2K17/ghz, > 16 specint2K6GHz*, new intels atom architecture, rk36XX gonna be watching... 8X cortex a730/c1 pro/ whatever inconsistent arm naming they just invented 10 seconds ago (8 cores), arms latest e-core architecture, > 2.2 specint 2K17/ghz, > 18 specint2K6GHz* (SHUT UP, INTEL!!! YOU ARE NOT INVITED TO THE PARTY) , up to 3.XX Ghz (reclassified since this intels e core levels cores and not p, sorry rockcjp) 4X cortex a730/c1 pro/ whatever inconsistent arm naming they just invented 10 seconds ago (4 cores), arms latest e-core architecture, > 2.2 specint 2K17/ghz, > 18 specint2K6GHz* (YOU THOUGHT YOUR "SKYMONT" TRASH WAS COOL, HUH?) , up to 3.XX Ghz (rockcjp is in 2022 with these technologies...)

tbh rockcjp is producing these on like tsmc n6 so its a l for them... intels got a muh better node...

conclusion: dpendeds on your choce. if you want an arm sbc, maybe the RK36294994192491532042032425 is the choice that you may love. lol. x9 3838588248219321499533124759132h might not be even for you if you demand absolute mt performance. try something else like 270k or threadripper. good bye...

Bonus:

arm c1-ultra, arms latest "x-series"core carchitescture, > 3.1 specint2k17/ghz, > 25 specint2k6GHZ, arm is straight up mogging intel and amd in their own game, arms cooking rn, only losing to apple, sad for arm, arm still hasnt been able to keep up, and rockcjp would never integrate that to their socs

x9 388h vs spacemit k3 processor???

yoshi_fp36 đã đăng vào 27, Tháng 5, 2026, 6:31

unfair comparison of two 16 core processors...

lets go

Spacemit k3:

8X X100 (2 clusters), X100 > Specint2K6/ghz of 9.0 (this is so funny), X100 supports the latest features, double pumped 256b vectors (compare: gracemont), Up to 2.5 GHZ...

8XA100 ("AI cores"), 15 TOPS inbuilt NPU, Based on older X60 architecture > Specint2K6/GHZ of 5.0, not accessible in normal usage, Only for AI CORES!!!, BIIIIIIIG VECTORS, 1024B VECTORS, 2X256B FMA (INTEL, YOU MUST LISTEN TO THIS, X9 388H, THEY ARE CATCHING UP!!). 2.0 Gjz..... because GJZ IS OUR SURVIVOR

CACHE: 4MBX2 (X100)+1MB X2 (A100) (again, gracemont would like to have a talk, its so funny)

X9 388H:

Cluster 1 4X coigar Cove (4 cores), Intels latest specint2k6 architecture, > 2.2 specint 2K17/ghz, > 18 specint2K6GHz* (listen up, X100? you thought HIGH PERFORMANCE means catching up to A76? LOLOLLLLL) , P cores, born from lion cove, node shrink of lion cove., 5.1 Ghz

8X Darkmont, node shrink of skymont. , 3.8 GHz

4x Lpe, which is going to still be more powerful than 8X X100 combined. LollllllUlz... 3.7 Gjz...

CACHE: 18M+3M * 4(L2)+4M*3(L2)

UNDOUBTEDLY THE K3 WINS. IN EVERY SINGLE THING. IF YOU WERE COMPARING BIIIIIG VECTORS, THAT IS.

* pretty sure if you used intel cheesemaxxing compilerz then it can get > 22 Specint2K6/GHZ. Just for lulz...

and we don't talk about the Arc B3XX (ceensored) GPU. It's not a fair contest to compare that to the greatest matrix engine ever.

as such i've collected some more details... looks like 4 engines that can do 8x16x8 matrix multiplications in A100... we'll wait for the next generation with X86's ACE to "compete" with this.

(compete? well... AMX is already 16c/52c for a full 16x64x16 matrix multiplication. Its so unfunny that I, X86 himself, would consider competing to something that's obviously miles superior....)

tuning test

yoshi_fp36 đã đăng vào 15, Tháng 5, 2026, 15:46

following the testing methodology mentioned in the previous blog, here's an example result:

CPU: R7 7840U

GPU: RTX 3080 @ PCIe Gen4x4 (this is a HUGE limitation, see below for why)

Model: Qwen3.6-35B-A3B-MXFP4_MOE.gguf, target ctx = 69632

ub ncm min pp4k@d8k tg128@d8k
512 32 294.34 49.2
1024 33 498.29 48.41
1536 34 609.46 46.83
2048 35 809.02 (only 1.9X faster than 1660 Ti, slower than a 3060 on full bus!) 46.52
2560 36 793.59 45.86
3072 37 785.74 (inconclusive)
3584 38 (not tested) (not tested)
4096 39 (not tested) (not tested)

As you can see ub=2048 only loses about 7% of TG performance for 2.7X PP performance.

Peak power is only 210W and prompt processing TPS is only 800tps, even slower than 2xT4 while the card on itself should be way better. As you can see ub=2048 already saturates the (pretty slow) PCIe bus. The result will definitely look a lot better given a proper link (4x the speed), since a GTX 1660 Ti already can saturate this link.

How to tune llama.cpp for free

yoshi_fp36 đã đăng vào 12, Tháng 5, 2026, 8:37

Here's a 100% legit tutorial to tune for llama.cpp MoE models. Very simple.

To start, you need to determine your target context size and other parameters (e.g. context size 64k, ctk q8_0, etc.). Enable flash attention.

We'll focus on the two main parameters: -ncm and -ub. Set the "batch size" -b to 4096 and left there.

Now, here's simple initial tuning:

If targetting maximum tg128, etc:

  • Decrease ncm until OOM, then increase ub in steps of 256 until reached 4096 or OOM. this is most effective when ncm = 0, but not really when ncm is high (see below).

Now, there's the option to do more comprehensive tuning. You can use this table as your template and change if neccessary.

here MAX can refer to your context size or [your context size] - 4096. Choose any but the former will leave a slight VRAM budget for other things.

ub ncm min pp4096 @ d8192 tg128 @ d8192 pp4096 @ dMAX tg128 @ dMAX
512 ... ... ... ... ...
1024
...
4096 (or OOM)

Basically you can do the d8192 tests first and see what fits you best (maximum tg or PP.) If you have low VRAM, chances that just setting ub to max won't change the tg much, but pp performance can literally double. After that you can test on depths with step size 4k from 0 to MAX.
