Newegg cuts AMD Ryzen 7 9850X3D price to $484, bundles free cooler and game

Newegg is selling AMD's Ryzen 7 9850X3D, currently the top gaming CPU on the market, for $484, roughly $15 under its original launch price. The deal throws in a 240mm Cooler Master AIO liquid cooler worth $79.99 and a copy of Onimusha: Way of the Sword worth $69.99 at no extra cost. The chip, an upgraded version of the 9800X3D announced at CES 2026, keeps the same 8-core/16-thread design and 3D V-Cache but adds a higher boost clock for a modest gaming performance gain.

Newegg bundles Ryzen 7 9800X3D CPU, X870E board and 32GB RAM for $1,109.99

Newegg is offering a combo deal pairing AMD's Ryzen 7 9800X3D processor with an Asus TUF Gaming X870E-Plus motherboard and 32GB of Corsair Vengeance RGB DDR5-6000 memory for $1,109.99. The package also throws in a 240mm Cooler Master AIO liquid cooler and a copy of Onimusha: Way of the Sword at no extra cost, saving buyers roughly $150 versus buying the parts separately.

Engineer shows how to make a spin-lock 5.7x faster and 5.4x more energy-efficient

A developer walks through optimizing a basic spin-lock implementation in C++, starting from a naive atomic exchange loop that slows dramatically under contention. Benchmarks show the naive version taking 3.14 ns uncontended but ballooning to 246 ns with four threads, driven by cache-line contention and branch mispredictions. Through iterative refinements, the author achieves a version that is 5.7 times faster and consumes 5.4 times less energy than the original.

OpenJDK JEP 544 adds AOT native code compilation to HotSpot JVM

OpenJDK's JEP 544 proposes extending HotSpot's existing AOT cache mechanism to store precompiled native code generated during a training run, making it instantly usable when an application starts in production. If workload behavior shifts, the JVM falls back to dynamic JIT compilation to maintain performance, blending AOT and JIT approaches without requiring any code or configuration changes from developers.

Simulation of 91,874 real agentic-LLM requests shows LRU still beats proposed KV-cache alternatives

A researcher replayed 68,266 requests from 393 Claude Code sessions and 23,608 Mooncake requests through a custom prefix-cache simulator, testing three approaches meant to outperform the standard LRU eviction policy used by vLLM, SGLang, LMCache and Mooncake Store. None of the alternatives beat the default LRU-over-radix-leaves baseline, and the analysis found that cache misses mostly come from rapid, seconds-apart tool-calling loops rather than sessions timing out after going idle.

DeepSeek to launch V4.1 Flash model, undercutting V4 Pro on cost and speed

DeepSeek confirmed it will officially release its V4.1 Flash model on September 10, 2026 (Beijing Time), stating internal testing shows it outperforms V4 Pro on performance, cost, speed, and task completion time. Until V4.1 Pro arrives, all Pro-model requests will be automatically redirected to V4.1 Flash and charged at the cheaper Flash pricing tier.

RTX 4090 teardown traces how STG.E writes results back to memory

A technical deep-dive follows the STG.E instruction—the global memory store operation in a simple vector-add CUDA kernel—through an RTX 4090's pipeline, from register read through the load/store unit, coalescer, L1 cache, crossbar, and L2 slice, down to DRAM. The author benchmarks how frequently a single warp can issue store instructions, finding a new STG.E can be pushed through the register file, LSU, and coalescer roughly every 6.1 cycles (about 2.3 nanoseconds at 2.6 GHz).

Cloudflare tests Zstandard compression in Pingora to shrink cache storage

Cloudflare built a prototype called Cache Transcoding, developed during an intern project, that compresses eligible cached assets with Zstandard before writing them to disk inside its Pingora proxy. Assets stay compressed while stored and while moving between data centers via Tiered Cache, then get decoded only when served to the client. Early tests show this shrinks eligible assets to about a third of their original size with only a small CPU overhead.

uv Python tool adds deduplication for wheel cache files

A pull request submitted to the uv project introduces a mechanism to deduplicate files stored in its wheel cache, reducing redundant copies of package files. The change was merged into the open-source Python packaging tool's codebase after review.

Smart TVs face storage limits as pre-installed apps and bloatware pile up

Most smart TVs ship with limited internal storage that quickly fills up due to app caches, temporary files, and manufacturer-installed bloatware that can be difficult or impossible to remove. Users can clear app cache through settings for temporary relief or uninstall unused apps, though bloatware removal is often restricted by manufacturers. An alternative workaround is attaching an external streaming device like a Fire TV Stick, Roku, or Google TV Streamer, which brings its own storage and app ecosystem independent of the TV's built-in memory.

Report explains why deleting app and browser caches often backfires

The report clarifies that caches are temporary storage used by browsers and apps to avoid re-downloading or recreating data like images, playlists and thumbnails. It notes there is no single universal cache on a device, since browsers, individual apps and the system each maintain separate caches for different purposes.

Cloudflare halves DNS cache memory, freeing 100TB across 1.1.1.1 network

Cloudflare reworked the Rust codebase powering its Big Pineapple DNS caching system, shrinking the average cache entry from 953 bytes to 420 bytes without adding any hardware. The changes—including replacing growable Vec and String types with fixed-size boxed slices and consolidating record storage into a single buffer—cut per-instance memory use from 9.3GB to 5.3GB while also boosting insert speed and lowering lookup latency.
