MSI is synonymous with gaming notebooks and the company’s Raider lineup is one of the top gaming platforms on the market. But, MSI has always kept a tiny bit back, reserving their most interesting ideas and most powerful configurations for their Titan lineup.
MSI’s Titan series always offers something special. Something different. Something unique. Look back to the insane MSI GT80 Titan from 2015 which featured a full desktop keyboard melded onto an 18.4-inch notebook computer. The MSI GT76 Titan packed in a full desktop Core i9-9900K processor into a more traditional 17-inch form factor.
Today we are looking at the latest iteration from MSI; the Titan GT77. Featuring a desktop-inspired Core i9-12900HX processor and an NVIDIA RTX 3080 Ti Laptop GPU, the GT77 is one of the most powerful notebooks on the market today.
Intel’s latest product for powerful notebooks is the Alder Lake HX-series of processors, which are part of the 12th Gen Core family. And although the naming for these chips is similar to Intel's traditional H-series, the new HX platform is significantly different. Intel’s HX processors are repackaged desktop processors rather than the laptop-focused H lineup. Compared to the Core i9-12900HK, the Core i9-12900HX offers an additional two P-Cores, bringing the total to eight, and it offers the same eight E-Cores. This brings the Core i9-12900HX up to a total of 24 threads, with 16 performance threads and eight efficiency threads.
Being a desktop processor, the maximum memory supported is also increased from 64 GB to 128 GB. MSI offers four DDR5 slots for users to upgrade their memory in the Titan GT77. The review sample came with 4 x 16 GB of DDR5-4800 system RAM for 64 GB total, running at DDR5-4000 speeds in a 2 DIMM-per-channel configuration.
Intel has also increased the base TDP from 45 Watts to 55 Watts, and the maximum turbo power level is a staggering 157 Watts, up from 115 Watts in the normal H lineup. For multitasking, assuming the laptop cooling solution can keep up, this should be a sizable increase in performance.
The one downgrade from the i9-12900HK is that the i9-12900HX offers Intel’s much less performant UHD graphics configuration (32 EUs), as opposed to the more powerful Iris configurations (48 - 96 EUs) in the H-series proper. However, as this processor is always going to be paired with discrete graphics, that is not going to be much of a hindrance.
The new HX-series is not a drop-in replacement on the H-series lineup so laptop vendors will have to incur the additional cost of creating bespoke motherboards. Not only is the packaging different, with the HX leveraging the FCBGA1964 package compared to the FCBGA1744 found on the normal H series, the HX is also back to a two-chip package, as there is no on-chip PCH in this desktop-derived processor. The high-end nature of the platform also means that laptops will also want to pack in four memory slots whenever possible (for maximum memory capacity), compared to just two on the normal H-series laptop designs.
Packing a desktop processor into a notebook computer is not a new concept and we have seen and reviewed several examples of this in the past, but Intel offering a proper notebook packaged option really changes the equation and allows notebook manufacturers to make fewer compromises if they do choose to go this route. They will need a unique motherboard for the HX-series, but the FCBGA package will allow them to reduce the Z-height of the system as they will not need to include a socket for the processor. The flip side of the new HX platform is that costs will be significantly higher than a traditional H-series processor due to the unique motherboard, as well as the additional memory slots. But, as we always see, there is an insatiable thirst for more performance especially with the rise in demanding workloads for video creation, engineering, and of course gaming.

On the graphics front, MSI has outfitted this Titan GT77 with the fastest graphics card available for a notebook right now: the NVIDIA GeForce RTX 3080 Ti Laptop GPU (henceforth known as the 3080L Ti). The 3080L Ti sits between the desktop RTX 3070 and RTX 3080 in terms of hardware available, and is paired with 16 GB of GDDR6 connected via a 256-bit bus.
On the networking side, MSI has gone with the Killer combination of Wi-Fi and Ethernet. The Killer AX1675i Wi-Fi networking solution is a Wi-Fi 6E product, meaning it supports the 6 GHz bands if your access point is new enough to have them. Killer is built on the industry-leading Intel Wi-Fi stack and if you do not want to use the software features Killer provides, you still get the best and most reliable Wi-Fi option as a base. Ethernet is a Killer E3100G 2.5 Gbps offering. On the networking side there is little to complain about.
As for storage, our review sample from Intel came equipped with three 1 TB Samsung PM9A1 PCIe 4.0 SSDs.
MSI’s Titan series is really a performance-first device and MSI has outfitted the Titan GT77 with absolutely everything they could think of. There’s even a Windows Hello IR camera and fingerprint reader. All of this is packed into a (relatively) compact package. Let’s take a closer look at that first.

meacupla - Thursday, September 1, 2022 - linkDDR5-4000 is really disappointing, even with 4x16GB.
Does it at least work in 4800 if you only use 2x16GB sticks?
BlakLanner - Thursday, September 1, 2022 - linkDisappointed at the 2.5G wired networking. My GT75 Titan had a 10Gb Aquantia NIC and I had a lot of use for that in my line of work.
Darnassus - Thursday, September 1, 2022 - linkIt sucks there's no 1440p version..
kpb321 - Thursday, September 1, 2022 - link"Being a desktop processor, the maximum memory supported is also increased from 64 GB to 128 GB.

This seems to be a little misleading because it makes it sound like the 4 DIMMs are needed for quad channel and this has a very wide memory bus but that isn't the case. DDR5 makes each DIMM into 2 channels half the width of DDR4 so the overall bus width is still the same. EG four 32bit channels instead of two 64bit channels. This is not four 64bit channels as that is still limited to HEDT/Workstation/Server products.
Ryan Smith - Thursday, September 1, 2022 - linkThanks. That's an unforced error on our part. That should (and now does) read "2 DPC configuration" rather than "quad-channel".
Technically, a 128-bit DDR5 memory bus is quad channels. But that's not the point we were trying to make.
shabby - Thursday, September 1, 2022 - linkAre the temperature charts missing on purpose? lol
deil - Tuesday, September 6, 2022 - linkThe whole thing is 3.3 KG, so I assume it's 2.5KG of heat pipes and copper/alu to get rid of it.
it's like 400W total of heat dissipation and yes I think thermals were excluded on purpose, forced by intel, or anandtech would not be able to post the review otherwise before full cpu release and NDA's expiration.
what I see is that it's just a hair above 5900hx, probably because it's not heat soaked all of that copper when tested.
This thing is a burst monster, and otherwise gaming crapware, not worth 5000$ at all.
100% it will be heat soaked in 5 min, and rest of the gaming session you will have both 50'C on your keyboard, and lower FPS.
If we comare that to 7'th gen AMD that is teased by AMD to be 60% higher than current series at 65W (so gaming laptop level) I expect 12900HX to be smeared on the ground like a biker who crashed at 300km/h.
deil - Tuesday, September 6, 2022 - linkI cannot redact my previous comment, but I think you can get to the point i was making.
What I see is you can make that point from battery life and charging, Massive battery and short lived on web, means it's a very power hungry setup.
3h to fill, 3h to discharge, comparing to AMD 2 hours to charge and 6h to discharge respectively. (with very similar 220W-250W bricks I am sure of it)
lemurbutton - Friday, September 2, 2022 - linkAnandtech lost a lot of good CPU review talent when Andrei and Ian left. Now we get the same old Cinebench benchmarks that Youtubers run.
Cinebench is a terrible CPU benchmark.
tamalero - Saturday, September 3, 2022 - linkWut? how the hell its a bad benchmark?
