AMD Ryzen 7 7745HX Beats Higher Priced 13th Gen Core i7 Mobile Processor Options in Gaming Performance and Battery

[btarunr]

AMD "Zen 4" processors offer unmatched efficiency at lower power, and notebook manufacturers are beginning to notice that the company's high core-count Ryzen 7045HX series "Dragon Range" mobile processors offer performance and battery-life highly competitive to 13th Gen Core "Raptor Lake" processors. The Ryzen 7 7745HX is an 8-core/16-thread processor with a single 5 nm "Zen 4" chiplet, and default TDP of 55 W. Chinese tech publication Golden Pig Upgrade reviewed a notebook powered by the 7745HX, and compared it with one rocking a Core i7-13700HX 8P+8E. The reviewer found the 7745HX to offer superior performance/Watt and gaming performance that either matches or beats the "Raptor Lake," which is held back by aggressive power-management and an older 10 nm-class process node.

Not exactly. I see this news in other sites where has this:

The Lenovo laptop in which the chip was featured comes with an 85W base TDP for the Ryzen 7 7745HX with an upper limit of 125/145W.

AMD already was leading in efficiency with Zen3+ based 6000 series. Looks like the 7000 series will take the performance crown too.

The main issue however is availability. Anyone who has tried to get AMD based laptop in the past can confirm that availability sucks. I hope that with silicon shortage being over and demand falling they can produce enough of these to make a dent in the market.

Lisa said during financial statement that availability is bad as they're not getting good margin from OEMs. OEMs apparently have enough inventory and they don't want more processors. Intel doesn't mind selling their chips at low margin as they've their own fabs. Intel also gives several support and incentives so it's much easier for them to sell more chips.

Exactly shouldn't be surprising. 13th gen is a retread with some more cache and some more E cores at best. The 7745HX is a node shrink, so any 6000 series advantages should be further increased. I'm sure if the Intel CPUs were made by TSMC they would be much better but you get the foundry product you have now. It's like Global Foundries holding back AMD in the past. It isn't equal unless they both use the best foundry. I'm looking forward to Apple's first 3nm products later this year.

The 7745HX is a node shrink...6000 series

Huh "6"nm->"5"nm I think this is not node shrink.

Is it silicone shortage or Intel's grip on OEMs?

Technically it is a shrink.

I was looking for a laptop with a AMD processor, the models that I was looking at doesnt have most of things I was looking into so I decided Intel.

Yet another misleading article by this writer. High Power efficiency at maximum loads doesn't mean good battery life. Ryzen is known and continues to have bad power efficiency at idle to medium loads, so unless AMD has fixed that, which the source article doesn't show or mention, the battery life won't be better than Intel.

You mean Intel has shady practices with OEMs that although technically legal, are not ethically in the interests of consumers or competition...let's not forget that Intel has been found guilty in multiple courts of bribing OEMs to NOT offer AMD...I'm not making that claim here, but I wouldn't be surprised if Intel is offering its chips to OEMs at such low cost they're probably barely profiting.

Mobility is the x86 consumer segment with a larger T.A.M. than desktop, so AMD's increased presence in this segment is very important both for AMD and for consumers who would undoubtedly benefit from increased competition and options. Unfortunately, rhe vast majority of consumers in this segment probably don't even know AMD exists and most likely assumes "Intel" is the only option and synonymous with "CPU". The more consumers have a positive experience with AMD however, the less Intel will seem omnipresent in this segment. I've had my Asus Zephyrus G14 (Zen2/RTX 2060) for a while now and couldn't be happier, and I think most consumers would have a similar experience if they just take the chance.

6nm is basically an enhanced 7nm. While the 5nm is an actual node shrink.

Have you watched any modern laptop reviews? AMD laptops can last up to 10 hours on Battery watching Youtube 2 years ago.

7745 is not a node shrink from zen3+. The 4 indicates it is Zen4.

Huh I think that missinterpretation was released.
Ps.
The whole problem is in trusting the trade names of the nanometers in the lithographic.

It is very close to being a node shrink. 6nm is an improvement upon 7nm by using EUV for more layers. The result is an 18% improvement in logic density (notice that nothing is said about SRAM density). N5, on the other hand, improves logic density by 80% compared to N7 though SRAM density only increases by 35%. In any case, the mobile Ryzen is using N4, not N5 so logic density is about 6% more than N5.

Ryzen mobile surpassed Intel a while back. It's difficult to compare laptops, but look at the figures from NotebookCheck's review of the Lenovo ThinkPad Z16 G1. Despite a 20% larger battery, the Intel laptop lasts one hour less on battery when browsing on Wifi.

How come AMD wins in all the battery life that I see. Maybe you should open your eyes.
