It's the other way around - they aren't doing many Icelake-SP wafers right now, based upon Intel's financials.
isn't the manufacturing tech of icelake SP the same like the U icelake?
as I understand superfin is different
so competition of wafers isn't so hot IMO

Yeah, I think ICL-SP is supposed to be fabbed with the same process as ICL-U (10 nm) and not the updated 10SF process.

Do we know of any other major products on 10SF other than TGL-U? It is my understanding that Alder lake and Sapphire Rapids will be fabbed with a newer process (10 ESF) next year.

exactly
bigger core (golden) and improved process
ICL-SP looks a little meh today

That Tiger Lake U Pentium looks to be every bit as good as The i3-1005G1 from the initial specs. Maybe it has a cut-down GPU section, but, given how well the 1005G1 does in regular day-to-day office and non-gaming home use, it'll be a good product.

The 1005G1 also has a cut down GPU.

Of course! I should have clarified that it may have a further reduced capability one than is in the G1's UHD 32 EUs. However, it may be a wash as Tiger Lake should have the Xe GPU, so its EUs should be more performant, and at that level or futher of cut-down, might still be faster.

The 48EU version is nearly twice as fast, plus it'll have better gaming optimizations. Even the 32EU should be quite a step up over the Gen11 G1. The G1's in i3 parts clock even lower than the i5 too.

Icelake was just mediocre that's all.

Never said it was great, but, in almost all cases, I’ll take an i3-1005G1 over an equally specced Ryzen 3200u laptop. On the market, up until a few weeks ago when the prices on the low end laptops went insane, the two were roughly equivalent in price.

The Black Friday Icelake sale was quite attractive. But now the competition is Ryzen 4000.

As for the graphics the Icelake G1 graphics outperforms UHD 620 by 70-80% in Witcher 3. The Gen 9 graphics were particularly weak in that game, and whatever Gen 11 does fixes that. The G7 graphics is 3x the performance of UHD 620 in that game. There are few other games that's like that as well. Even Gen 11 has weaknesses. It seems to be especially true for Intel GPU architecture GPUs, telling us of the low level it was starting from.

This is why the average gains don't show everything for a new architecture. In such scenarios the Xe should outperform Gen 11 by 2.5-3x.

Referring back to Witcher 3, the better implementations of the Tigerlake laptops should enable 40 fps in 1080p High settings. You may need to get some settings down to Medium to get it to 50 fps for playability but its a monumental advance.

If true, that is pretty amazing for an intel IGP. With only a quad core cpu, I would be concerned about stutter as well.

Gen11 came a long way. It's still not a full match for the vega iGPU in AMD's mobile product when comparably configured, but, that's the rub, isn't it? G1 is more iGPU resources than Vega 3 in the 3200u, and it shows when you benchmark things. The single thread performance of the bottom rung i3-1005G1 is notably faster than the same metrics on the 3200u. I really wish that AMD had produced a non-pro 3300u that was available for a few dollars more than the 3200u, but you can't find anything with the 3300u for less than almost double the price of a comparable 3200u laptop, and once you've moved to that price rung, the i5-10xxG4 and G7 enter the picture, and it's still a no contest situation.

One thing we were wondering about Gen 11 is despite the 2.7x increase in EUs, ROPs and TMUs, we got ~2x improvement. I chalked it up to possibly bandwidth not doubling, but there's one definite regression in Gen 11 per EU over Gen 9.

Each EU in Gen 9 has two pipes each capable of 4x FMA or INT ops. The second pipe also has the capability of handling extended FP math operation. In Gen 11, only one of the pipe is capable of doing INT ops and is same as Gen 9 for extended math.

In Xe/Gen 12, they combine two EUs into one "fat" EU. But if you look at it from a "thin" EU perspective as with the predecessors, both its pipes are capable of INT ops as with Gen 9.

Gen 9 Int32 capability per EU = 4x 2 ALUs
Gen 11 Int32 capability per EU = 4x 1 ALUs
Xe Int32 capability per EU = 4x 2 ALUs

So Gen 11 despite 2.7x the hardware elsewhere, in integer it only improves by 33%. Compared to Gen 11, Xe is 3x the performance for integer operations. In Xe, the extended math operations can operate without clogging up Int/FP operations unlike the predecessors.

According to Nvidia, for every 100 FP operations there are an average of 36 INT operations.

Games are increasingly using integer operations and in those modern games Gen 11 might not show as big of an advantage over Gen 9.

If true, that is pretty amazing for an intel IGP. With only a quad core cpu, I would be concerned about stutter as well.

A good Icelake implementation gets ~20 fps in Witcher 3 1080P High.

As for stuttering a high performing dual core desktop is just as capable as a lower performing quad core laptop. Problems in laptops are not only low clocks but power management settings. It's not a simple matter of balanced/high performance settings, as sometimes the balanced configuration can perform better. There are more than a dozen settings a manufacturer can tune.

Following: the i3-1005g1 just doesn't have problems with thermal throttling with anything approaching a competent cooling solution. It'll boost to the power limits all day long. Itshe quad cores that seem to have issues.

Ryzen 7 4800U has only 23FPS in Witcher 3 FullHD with high settings and I don't think tiger Lake will be 74% faster even If we use the 28W version.
On the other hand ice Lake 64EU manages 20FPS in the same game, even though It's 32% slower in Firestrike than Renoir. This just shows Firestrike score doesn't represent the actual gaming performance, so even Tiger Lake could be slower in real games compared to Ice Lake.

Even If It doesn't manage to achieve 40FPS, It will be the fastest IGP.

Icelake being close to 4800U in Witcher doesn't mean Firestrike doesn't represent gaming performance. It just means Icelake's Gen 11 is particularly strong in Witcher 3. Other games are out there where the differences are greater than in Fire Strike. Representation doesn't mean exact equality.

Overall, when you compare top systems, the difference in games between Gen 11 and Renoir are pretty close to the differences in Fire Strike.

Yes it's true Firestrike isn't far off from (DX11) real world. And btw Gen11 seems to need more power relative to Renoir Vega, there is little game performance difference between 15W and 25W on Renoir whereas Gen11 improves a lot more from its TDP up 25W. This is why the premium devices using Gen11 may be not that much slower than Renoir in gaming, because they are usually using TDP up 25W (if not more).

About Xe LP, one major difference is this to both Gen9 and Gen11:

Update: Intel has since shot me a note stating that they have in fact upgraded their geometry front-end, so this is not the same 1 triangle/clock hardware as on earlier Intel GPUs. Xe-LP's geometry frontend can now spit out two backface culled triangles per clock, doubling Intel's peak geometry performance on top of Xe-LP's clockspeed improvements.

3.1 Ghz base is odd, the fastest I7-1185G7 has a 3.0 Ghz base as far as we know.
There's no way around it, it's gonna be a magnificent CPU in so many aspects. Such a shame - mainly for intel - that 10nm yields don't allow it to come to desktop. I can't really work or do anything productive on a laptop for more than 30 minutes, let alone play games.

You can always dock it right? I have a laptop from work, I hardly ever use it undocked unless in meeting rooms to login into the online meeting. Or do you mean due to the performance? I agree the trackpad, keyboard and more so limited screen space make any real work a problem.

It will be a great CPU probably , its funny to see that Intel lost so much momentum that it seems like everyone are looking for faults and the "trick" as ppl can no longer believe Intel can create the best CPU`s again , AMD did get a lot of mindshare with Zen.

Yes. I do have a laptop, and cloud services pretty much make docking redundant (for me), which is very fortunate, as I hate to plug several things in and out instead of just switching on a single thing. So I'm actually quite fond of the fact that I'm allowed to have a normal desktop at work. I'm not kidding, even just navigating in Windows is a pain in the bottom for someone like me, who uses almost evety keyboard shortcut there is, and types relatively fast - on a nornal sized keyboard.

Well all you have to do is refer to history. Intel made a lot of strides in over 50 years, but they were outdone by AMD many times. Intel may be down for the next few years, but they'll come back eventually. Consumers should never favor one side over another or rather they shouldn't wish for Intel to be down forever or go away. We'll have another Core situation on our hands with AMD at the top. Competition is always good for the consumer.

Well, I prefer one over the other. It was Intel (286,386,486) Then AMD (K5,K6, Athlon), Then Intel (conroe Conroe, to to whatever in 2016), Now AMD again.

I swing with whoever is best at the time.
