Bring us the A725 vs X925 cage match
Arm's Cortex A725 Ft. Dell's Pro Max with GB10
Fans demand A725 vs X925 face-off as buyers say it feels like Ryzen
TLDR: Arm’s mid-size A725 core shows up in Nvidia’s GB10 alongside big X925 cores, earning praise for quiet performance in Dell’s mini PC. Comments demand a direct A725 vs X925 showdown, while one user says the GB10 feels as fast as their Ryzen rig—fueling debate over ARM’s PC readiness.
Arm’s new Cortex A725 just rolled into Nvidia’s GB10 chip inside Dell’s “Pro Max” mini PC, and the comments turned into a hype train with a hornet’s nest strapped on. The article says A725 is a smaller “many-at-once” core paired with beefy X925 cores (10 of each), and testers praise Dell’s box for staying quiet under heavy load. Under the hood talk—like the A725’s “guessing-ahead” brain (branch predictor) taking a tiny step back in one area while still sparring with Intel’s small “efficiency” cores—had spec nerds leaning in, but the crowd was here for the showdown.
Top vibe: Give us the A725 vs X925 fight. User crest demanded the direct duel everyone craves. Meanwhile, pinnochio roasted the label with the instant-classic joke—calling the title “sliced tomato featuring BLT sandwich”—and the meme wrote itself. Then cmrdporcupine dropped a real-world bomb: their ASUS GB10 feels so smooth they forget it’s ARM, and it runs about like their Ryzen 7940HS mini PC, with more cores and RAM. Cue the split: one camp chants “ARM is laptop-ready,” another wants receipts and side-by-side charts. Corporate flex note: Dell sent units and scored props for the cool-and-quiet build. Bottom line? The community’s buzzing: small cores are getting scary good—now show the big vs small cage match. Read the deep dive by Chester Lam and peep Dell’s box here.
Key Points
- •Nvidia’s GB10 integrates ten Cortex A725 and ten Cortex X925 cores across two clusters, with A725 at 2.8 GHz and X925 at 3.9–4.0 GHz.
- •One GB10 cluster has 8 MB of shared L3 cache and the other 16 MB, connected via Arm’s DSU-120 with 256-bit read/write paths.
- •Cortex A725 is a 5-wide out-of-order core with reordering capacity comparable to Intel Skylake and AMD Zen 2.
- •A725’s branch predictor performance is similar to A715 but its BTB configuration regresses versus A710, including a 512-entry L1 BTB with higher latency at larger levels.
- •Compared to Intel Skymont E-Core, A725 excels in tiny loops with taken branches, while Skymont leads at moderate branch counts due to its 1024-entry, single-cycle L1 BTB.
