Precision 7750/7550 release date?

I get the feeling that Intel targeted the 10th Gens to be faster than their predecessor within families. So the i7-10875H is 3-33% faster than the i7-9750H. Since I feel like either the chips are not available or are under NDA, we do not yet know if the i9-10885H is faster than the i9-9880H. That means the current 7550/7750 top config with a Quadro RTX 5000 and the i7-10875H will be more CPU bound than the i7-9750H but it remains unknown if bumping the CPU to an i9 will be less CPU bound than the 9th gen 7540/7740 with i9-9880H. I'm trying to put a purchase recommendation for 10's of these things together and I can't get behind the i7/RTX 5000.

Not sure why the i9 is not available yet, but they will let you purchase the Xeon W-10885M which should have the same performance characteristics as the i9. (And the cost difference between the i9 and the Xeon would be a drop in the bucket, if you are considering the RTX 5000 GPU.)

 

Yeah, the Xeon and ECC memory is a 10% premium. Might be the same up-charge to go from i7 to i9... also, the Xeon/ECC is 2666 v. 2933 for non-ECC. Again, ugh...

On the 7740 all CPU's were limited to 75W sustained TDP, so the 8-core processor options all performed about the same. Given that the i7-10875 is an 8-core part with hyperthreading, it should perform similar to the i9-9880 with the same constraints. It basically just drops the i9 branding from what I can tell.

 

Do you think they'll incorporate the i9 in the future or just stick with the i7-10875?

 

Spec sheet shows that a Core i9 10885H is supposed to be an option. 2.4 GHz / 5.3 GHz turbo, like the Xeon with the same number attached. I agree that it will probably perform about the same as the top i7. Same cache, core count, and power limit. (I guess back in 9th gen, they didn't have any 8-core i7 CPUs.)

 

But the benchmarks I linked to indicate that the i9-9880H smokes the i7-10875H, even with 8 cores/16 threads. The i9-10885H seems to have a higher clock and better cooling than the 9880 owing to reduced silicon thickness and increased IHS thickness.

Many variables like TDP limits, cooling system efficiency, security patches can effect performance. If the numbers are important to you then it would be best to hold off on a large purchase until we have a few samples of how each processor performs in this machine.

 

I have a 7550 on the way. Upgrading from 7540 w/ 2286M, RTX 3000, UHD. Hoping that this new machine will have a smoother fan control (instead of the stepped and fixed 5 speeds that the current Dell EC uses). New unit also doesn't appear to be as robust, judging from the teardown photos in the Service Manual. Motherboard and display hinge is screwed into the plastic palmrest instead of a dedicated metal frame like on 7540 and prior models. Heatsink no longer has side vents but rear vents are larger; we will have to see if this has any detriment on cooling or not.

Nice! Consider performing benchmark comparisons between the two, and do start up a 7550/7750 Owners' Thread
