Question Intel 275HX vs AMD 9955HX3D temps/fans/perf

[fastandfurious6]

Anyone got a new Intel 275HX laptop? How is it running, temps fans perf wise?

basically there's no good 9955hx3d product, only tongfangs and ludicrous MSI behemoths
the best zen5 is asus strix but no hdr no oled
intel laptops have literally everything plenty of stock

Legion is the best product and the AMD variant is limited to 5070 nonTi and literally zen 4 dragon range https://psref.lenovo.com/Product/Legion_Pro_5_16ADR10 ....

Yup, Strix G16/G18 w/ Zen 5 CPUs are fast, but panel options suck for creators. Mostly 500-nit, no HDR, no OLED, gaming only focus.

intel laptops have literally everything plenty of stock

Intel has the OEM design wins this gen, OLED, mini-LED, mux, Thunderbolt, everything bundled. AMD's top-end still feels like an afterthought outside niche configs.

Legion is the best product and the AMD variant is limited to 5070 nonTi and literally zen 4 dragon range

Exactly. No Zen 5 X3D + high-end GPU in Legion = wasted potential. AMD's top silicon stuck in niche or bulky systems. If you want balanced thermals + features, Intel has the better laptop ecosystem right now.

is 275hx actually balanced thermals and high perf? no stutters no lag? just the main drawbacks being E-cores and lack of 3D cache?

275HX performs more or less like a 9955HX non-3D and has a better battery life / less consumption when idle (due to the I/O die and packaging stuff of FIre Range not being strictly optimized for the mobile ). Power consumption under load is similar. Fire Range is a dedicated gaming chip, however, so battery life is a second thought on this class of notebooks, even if there may be niche cases where one can find it useful.
Apart from this, the ASUS choice to castrate the AMD chip with the 5700Ti as highest end pairing, is completely idiotic. On one side, I can see if some OEM don't push the Fire Range because Intel has chips that can cover more than one market and they have still good performance for gaming. But, once you decide to build a laptop with Fire Range and decide to use the 3D version, it has zero sense to not pair that laptop with the highest end mobile GPUs. It has sense only if you ger economic incentives for NOT using it - oh well.
Apart this, Tongfang and MSI products are good machines (even if I still don't understand the choice of WiFi and no USB4 on the Tongfangs) with great screens. Yes, MSI are bulky. But you can always find a lighter ans smaller laptop. Just not with this level of performance.
But in definitive, yes, it would be good for the consumer to have more choice in every market segment.

no stutters no lag?

Balanced depends on the chassis. In a Legion 9i or Scar 18:

• Sustained perf is excellent (PL2 150-190W sustained if cooling allows)
• No stutter/lag if drivers & power profiles are set right (Intel thread scheduler has matured)
• Temps can hit 100°C fast without undervolt/fan curve tweaks
• E-cores still mess with some low-thread latency workloads unless tuned (some games/emulators show microhitching)

just the main drawbacks being E-cores and lack of 3D cache?

Exactly. E-cores = good for background load, but hurt deterministic latency in some pro/gaming cases.
Lack of 3D V-Cache = big delta in sim, emu, CPU-heavy gaming vs 9955HX3D (up to 25-30% in 1% lows).

Legion 7/9 + mid-high RTX = best thermal/perf tuning out of the box.
Only downside lately is OEM gimping AMD configs, so Intel gets the better bins + panels.

these what I'm worried about

e-cores sounds like best to just disable them lol. does that increase overclockability/UV of P-cores as well?

every hwinfo review I see clearly shows "Core Throttling: YES" 🤣

there ain't no way 275HX is going to win against 9955hx3d in games

e-cores sounds like best to just disable them lol.

Disabling E-cores can actually help with:

• Cleaner thread scheduling (no bouncing between P/E)
• Slight thermal headroom boost > more stable clocks on P-cores
• Can reduce power draw spikes in light-to-mid loads > helps undervolting margin

But:

• Not all BIOS allow full E-core toggle
• Some apps (encoding, multitask) lose efficiency
• Still capped by OEM voltage/frequency locks (esp. in non-HX overclockable SKUs)
